A gunpowder magazine is a magazine (building) designed to store the explosive gunpowder in wooden barrels for safety. Gunpowder, until superseded, was a universal explosive used in the military and for civil engineering: both applications required storage magazines. Most magazines were purely functional and tended to be in remote and secure locations. They are the successor to the earlier powder towers and powder houses.
Historic magazines were at the following locations, among others:
There are magazines at:
The Ballincollig gunpowder mills were first opened in the late 18th century and were bought, in 1804, by the United Kingdom of Great Britain and Ireland's Board of Ordnance to help defend the Kingdom against attack. They were one of three royal gunpowder factories; but the Ballincollig mills became disused after the end of the Napoleonic Wars. They were sold off by the government in 1832, in a semi-derelict condition; but were bought by a Liverpool merchant and were reopened to manufacture gunpowder; finally closing, just over a century ago, in 1903. Many buildings survive and, together with the associated canals, were incorporated into a regional park – Ballincollig Regional Park. The site contains a number of powder magazines, as well as Expense magazines. [1]
The No. 2 magazine was built by the Board of Ordnance and is the oldest magazine. It is 29-foot (8.9 m) long by 28-foot (8.6 m) wide. It has a groin-vaulted roof. The magazine is protected by earthen banks on two sides; with doors at both ends. The No. 1 magazine is newer; and was built sometime after 1828. It is 80-foot (24.5 m) long by 25-foot (7.6 m) wide and has solid walls, but is now roofless. [1]
There is a surviving magazine at Camden Fort Meagher, part of the defences of Cork Harbour.
Rocky Island, midway between the mainland and Haulbowline Island (which at the time was an ordnance depot), is dominated by a magazine complex dating from 1808; it held up to 25,000 barrels, and was the principal store for the whole of Ireland. In 2007 it was restored and converted into Ireland's first crematorium outside Dublin. [2]
The Order of Saint John built a number of gunpowder magazines in Malta during their rule of the islands. Until the end of the sixteenth century, echauguettes were used to store gunpowder. The Order also built a magazine in Valletta, but this exploded in 1634, killing 22 people. After the explosion, a new magazine was built in Floriana, which was sparsely populated, to avoid another disaster. Various other magazines were built over the years, and their designs were influenced by French military architecture, particularly the style of Vauban. The British, who took over Malta in 1800, also built a number of magazines on the islands. [3]
Gunpowder magazines in Malta include:
In addition, some of the coastal fortifications also had their own magazines or storage areas.
In the Netherlands three gunpowder magazines still exist. The Kruithuis in Delft, the Kruithuis in Den Bosch (the oldest, built in 1618–1620) and one in Wierickerschans.
Gunpowder magazines were called Bārūt-Khāneh (Persian : باروتخانه, or باروطخانه) in Persia (Iran).
Gunpowder Manufacturing of Yusef Abad (باروت سازی یوسف آباد), and later the Gunpowder Magazine of Tehran (باروتخانه تهرانBārūt-Khāneh-ye Tehrān), was a gunpowder magazine near Tehran which was built during the Qajar dynasty. Nothing remains of this building today, and its exact location is unknown. [6]
A magazine was erected in Bathurst, East Cape, by the British military in 1821; it is still standing. It usually carried about 273 kg gunpowder, 7,000 ball cartridges and 60 rifles as stock. In 1870 the British military built a powder magazine in the Northern Cape town of Fraserburg (also still standing) in case of war with the neighbouring Griqua people and subsequently used in the Anglo-Boer War.
Gunpowder magazines were called Baruthâne in Turkish. In Ottoman Empire some magazines were built in Istanbul, Gallipoli and Saloniki. Among these Bakırköy gunpowder magazine is the only place to survive until today, was built in 1700. [7]
Production of gunpowder in England appears to have started in the mid-13th century with the aim of supplying The Crown. [8] Records show that gunpowder was being made in 1346, at the Tower of London; a powder house existed at the Tower in 1461. [8] Gunpowder was also being made or stored at other royal residences such as Greenwich Palace (the reason being that these were where the royal armouries were based). It was also stored in Scotland, in royal castles, such as Edinburgh Castle. Gunpowder manufacture at Faversham began as a private enterprise in the 16th century.
From the 18th century, efforts began to be made to site magazines away from inhabited areas. Nevertheless, storage at the older established sites persisted well into the 19th century.
The use of gunpowder for both military and civil engineering purposes began to be superseded by newer nitrogen-based explosives from the later 19th century. Gunpowder production in the United Kingdom was gradually phased out during the mid-20th century. The last remaining gunpowder mill at the Royal Gunpowder Factory, Waltham Abbey was damaged by a German parachute mine in 1941 and it never reopened. [9] This was followed by the closure of the gunpowder section at the Royal Ordnance Factory, ROF Chorley, the section was closed and demolished at the end of World War II, and ICI Nobel's Roslin gunpowder factory which closed in 1954. [9] This left the sole United Kingdom gunpowder factory at ICI Nobel's Ardeer site in North Ayrshire, Scotland; it too closed in October 1976. [9] Since then gunpowder has been imported into the United Kingdom.
Gunpowder magazines survive at several locations in the UK. It can be seen that, in many cases, the gunpowder was stored in locations which were both remote from habitations and could be made secure. They were also often sited in dense woodland (or had trees planted around them) as a way of lessening the effect of any explosion.
The Gunpowder Magazine in Berwick-upon-Tweed was built in 1745 to service Berwick Barracks and sited at a safe distance from them to the south. It is a solid stone building, heavily buttressed, windowless, stone roofed and enclosed by a stone wall. Along with Purfleet and Tilbury it is one of the few surviving eighteenth-century gunpowder magazines in the country.
Brean Down Fort was one of a number of Palmerston Forts built to defend the British, Irish and Channel Island coastlines. It was originally built in stages between 1862 and 1870; to protect the Bristol Channel. It had a large, underground, main gunpowder magazine, 15-foot (4.5 m) by 18-foot (5.5 m) by 20-foot (6.1 m) high, built to the recommendations of the 1863 Royal Commission. The magazine still exists. A further two, smaller, underground magazines, No. 2 magazine and No. 3 magazine, were also built. No. 3 magazine exploded on 3 July 1900 destroying most of the barracks. Gunner Hains was killed. It was concluded that he had killed himself by firing a ball cartridge down a ventilator shaft into the magazine which held 3 tons (3 tonnes) of gunpowder, causing the magazine to explode. [10] The fort was reused in both the First and Second World Wars; and additional expense magazines constructed. The fort is now owned by the National Trust.
As early as 1461, the Tower of London included a 'powderhous' within its walls. With the establishment of the Board of Ordnance there, its use as a gunpowder store increased. In the Tudor period the White Tower was refitted for this purpose, and by 1657 the entire building, apart from the chapel, was being used to store gunpowder. [11] Gunpowder was still being stored there when the Ordnance Board was disbanded in the mid-nineteenth century.
HMS Talbot was moored in the Thames at Beckton as a powder magazine in the late 19th century.
The Board of Ordnance maintained magazines at both Tilbury Fort and New Tavern Fort, which face each other across the River Thames. Two sizeable magazines of 1716 remain in place at Tilbury.
Purfleet Royal Gunpowder Magazine was established by Act of Parliament in 1760, built to the design of James Gabriel Montresor and opened in 1765, with a garrison in place to protect it. [12] Previously, gunpowder had been stored on Greenwich Peninsula, [13] but fears of an explosion there prompted the building of this new establishment further afield. The purpose of Purfleet was to store newly manufactured gunpowder, prior to its distribution elsewhere.
Purfleet was centred on five large magazines, each one capable of holding up to 10,400 barrels of gunpowder. These substantial brick-built sheds were windowless, with copper-lined doors and sand-filled roof voids – all designed to prevent (or mitigate the effects of) an explosion. [14] By the end of the eighteenth century, Purfleet was receiving regular consignments of powder from Waltham Abbey, to provide both the Navy and the Army with supplies.
The Ministry of Defence finally closed and sold the site in 1962, and several buildings were demolished to make way for a new housing estate. Some significant original buildings remain, however: the clock tower, the proofing house (in which samples of new consignments were tested) and one magazine. This magazine, No. 5, has been designated a Scheduled Ancient Monument and now houses the Purfleet Heritage and Military Centre, a vast collection of local and military memorabilia open to the public. [15] According to English Heritage, it represents (along with the magazine at Priddy's Hard in Gosport) "the most outstanding example of a typically British type of magazine, with twin barrel vaults, that relates to a critical period in Britain's growth as a naval power in the decades after the Seven Years' War." Inside, a good number of original features have survived, including some unique wooden overhead cranes, early forerunners of the gantry crane. [12]
A sizeable magazine stands in the unexpected surroundings of London's Hyde Park. Opened by the Board of Ordnance in 1805, its structure is similar to other British magazines of this period except for the fact that the exterior is more ornamented here than elsewhere (probably in deference to its setting) with a Palladian style portico and other features. [16] The magazine provided the army with a stock of gunpowder in the capital, in case of 'foreign invasion or popular uprising'. It remained in MOD hands until 1963, after which it served as a storage facility. Since 2013 it has had a new lease of life, having been refurbished and extended by Dame Zaha Hadid, as the Serpentine Sackler Gallery. [17]
In Plymouth the Board of Ordnance set up Powder Magazines to serve the fleet and defences of Devonport Dockyard initially at the Royal Citadel (later supplemented by a small magazine at the New Gun Wharf (Morice Yard) in 1720); but space was limited and people were living close by, so the Board sought a new, more isolated spot for its Magazines. They first settled on a site at Keyham Point (just north of Morice Yard) in 1775; but with that land required for an expansion of the Dockyard in the mid-19th century a new site was acquired further to the north, at Bull Point.
A magazine of 1744 survives in situ at Morice Yard (which today forms part of HMNB Devonport). Built to replace the earlier small magazine, which stood at the centre of the site, this is Britain's oldest surviving naval ordnance magazine. [18]
The Royal Navy Ordnance Base (later RNAD) Bull Point was the last great work of the Board of Ordnance before its disbandment in 1856. Bull Point was and is unusual in the unity and precise purpose of its design: rather than developing gradually over time, it was planned as a whole, and with a particular view to meeting the storage needs of emerging new types of artillery. Four Magazines were built (1851–54) each holding 10,000 barrels. These were followed by a series of other buildings specifically designed for particular uses. From the start, the site was fully integrated with the adjacent St Budeaux Royal Powder Works on Kinterbury Creek (established in 1805), where damaged powder was treated before being passed on to Bull Point for storage.
The buildings are mostly still in place within the MOD Bull Point RNAD site: all of one style, mostly ashlar with rock-faced dressings, they are said by English Heritage to comprise "both the finest ensemble in any of the Ordnance Yards and a remarkable example of integrated factory planning of the period". [19]
Building work on the Square Tower, Portsmouth, started in 1494; and from the end of the 16th century until 1779 it was used as a powder magazine, with a capacity of 12,000 barrels of gunpowder. [20]
The inhabitants of Portsmouth petitioned the Master General of the Ordnance in 1716 to remove the gunpowder, as they were worried about the hazards it posed to the town, but nothing was done at that time. A further petition was sent to the Board of Ordnance in 1767 following an explosion which caused extensive damage. This led to the construction of the Priddy's Hard magazine at Gosport (see below), in a remote area, across the water from Portsmouth.
The Square Tower still exists. After 1779 it was used for other purposes; including employment as a semaphore station in 1817. [20]
Priddy's Hard began life as Priddy's Hard Fort; however in 1768 King George III authorised the construction of a gunpowder magazine inside the ramparts to avoid having to store gunpowder in the Square Tower, Portsmouth. Construction was begun in 1771 and the magazine was in use by 1777. A cooperage and shifting house were built alongside at the same time, together with a 'rolling way' for moving gunpowder barrels between the magazine and a nearby wharf; together with the Magazine they are all Grade I listed structures. [21] [22]
Both the fort and the magazine came under the control of the Board of Ordnance until 1855; control passing, first to the War Office, and then the Admiralty in 1891. Priddy's Hard became a Naval Armaments Depot, finally closing in 1977. [23] The magazine now forms part of the Explosion! Museum of Naval Firepower.
In the 1780s the Duke of Richmond, Master General of the Ordnance, began to implement a policy of dividing gunpowder stored at the principal coastal locations, and storing it across several sites in the vicinity (to make it less vulnerable to a targeted attack). At Portsmouth, this led to the building of a new magazine at Tipner Point in 1796–8. A second magazine was added in 1856 (part of a policy of expansion following the Crimean War); both still stand flanked by two buildings, the former cooperage and the shifting house, which, along with the magazines, are listed buildings. [24] The magazines remained in use until the 1950s. The surrounding land is earmarked for future redevelopment as part of the Tipner Regeneration scheme. [25]
Another magazine depot for Portsmouth was established at Marchwood, where three magazines were built in 1814–16 to an innovative design by Sir William Congreve. Movement of gunpowder barrels within the complex was by canal. Four more magazines were added in 1856, and by 1864 Marchwood was Britain's largest magazine complex with capacity for 76,000 barrels. [26]
Two magazines have survived (one of 1814–16, one of 1856) along with some ancillary buildings (one of which is now home to Marchwood Yacht Club). [27] None of the other magazines has survived, mainly due to the damage that was sustained across the site during The Blitz. The depot closed in 1961; the site is now primarily a residential area.
Magazine Cottage in Sedgeford was built during the 17th century by the Le Strange Family as a gunpowder store during the English Civil War. [28] It is now a residential house and a landmark for the many walkers of the ancient Roman road Peddars Way; it is said that a secret passageway led from the house to the coast.
In 1668, following the Dutch Raid on the Medway, Upnor Castle was reassigned from serving as an artillery fort to be 'a Place of Store and Magazine'. Thenceforward, barrels of gunpowder were transferred to Upnor, primarily from the Tower of London. The castle was recognized as unsuitable for this role as early as 1808 when a new magazine (since demolished) was built on an adjacent site; another, of similar design, was added in 1857. [29] The latter, which still stands, is described as 'a particularly fine magazine building of the 1850s, distinguished by its historicist style' and 'the most impressive example of a magazine using the catenary arch system'. [30]
In 1877, five more new magazines were built inland at Chattenden (the two sites being linked by a railway). Still more magazines were built close by at Lodge Hill, from 1898, primarily for storing the recently developed explosive cordite. Upnor, Chattenden and Lodge Hill depots remained in military ownership until the mid-2010s, when the MOD marketed the land for housing and commercial use. [31]
Gunpowder magazines still survive at the Waltham Abbey Royal Gunpowder Mills, including its Grand Magazine, first constructed in 1804 and rebuilt in 1867–68.
The former Ordnance Depot at Weedon Bec includes four magazines dating from 1806 to 1810, along with another built in 1857. The magazines stand in their own compound apart from the main storehouses within a containing wall. Each magazine is separated from its neighbour by an earth-filled 'traverse' building, designed to absorb the impact of an explosion – the first time large magazines had been provided with traverses. Like all the main buildings at Weedon, the magazines lie along the bank of a branch of the Grand Union Canal for ease of transport. In 1827 the four magazines contained 10,500 barrels of powder, along with 1,463,700 ball and 693,746 blank cartridges. [29]
The hexagonal Old Powder Magazine still stands near the ruins of the Charles Bathurst Smelt Mill in Arkengarthdale, North Yorkshire. It stored gunpowder for use in the numerous lead workings in the area and was last used as a candle factory. All lead working in the dale ceased around 1911.
The remains of old storage magazines are prominent in the landscape around the old Nobel's Explosives site in Ayrshire, many protected by large earth banks which acted as blast walls; these are not all gunpowder magazines, as the site has long been associated with other explosives, particularly dynamite and ballistite.
A gunpowder magazine was located near the site of the Low Well in the village of Barkip, also known as The Den, near Beith, North Ayrshire.
An explosives magazine at the old Hessilhead limestone Quarry near Beith in North Ayrshire had a small section for blasting caps and a larger section for the sticks of Dynamite.
A restored powder house at Culzean Castle stands close to the sea cliffs. It was used to store gunpowder for the battery and for the 8am daily cannon shot.
Dockra limestone quarry lies between Barrmill, Broadstone and Gateside and had two gunpowder magazines; the older one was built some distance from the works. The quarries closed before WW2.
Dumbarton Castle contained two powder magazines; both located high up on Dumbarton Rock. The oldest went out of use in 1748, being replaced by a new Magazine designed by William Skinner. The new magazine, located on The Beak, has a barrel-vaulted roof, with double doors and indirect ventilation. It was designed to hold 150 barrels. [34]
Fort George was built between the end of the Jacobite rebellion of 1745 and 1769. The Grand Magazine was designed to hold 2,500 barrels of gunpowder. It was constructed between 1757 and 1759; and was built strong enough to withstand a direct hit from a mortar. It has a slate roof laid on brick vaults, which sit on stone pillars. To prevent sparks, no iron fittings are used in the magazine: the wooden floor is held by wooden dowels; and the doors and shutters sheathed with copper sheet. [35]
The Pouther (Scots for Powder) House in Irvine (Map reference: NS 3238 3847), North Ayrshire, Scotland is a rare survival and was possibly first constructed in 1642, as records show that orders for large quantities of gunpowder were met in 1643, 1644, and 1646. James VI, of Scotland, had instructed that all Royal burghs should have powder magazines. The saltpetre derived from deposits in byres, stables and doocots would be stored in the Powder House.
Plans for rebuilding it were made in 1781, at the time of the Napoleonic Wars, and accomplished by 1801; its use was discontinued in 1880. [36] The last use of the building was by Davidson the Ironmonger who stored carbide here for the miners. [37] When the Golffields wash-house was demolished in 1924, its slates were saved by Provost R M Hogg for restoration of the Powder House, a rescue assisted by Rev. Ranken of the Old Parish Church. It was repaired in 1961 and again in 1992 by Irvine Development Corporation. [38] It is an attractive and well built octagonal building topped by a weather cock.
The 1870 print [33] shows that it was placed in a remote situation, a golf-course being developed around it in later years and when this closed it remained, still fairly remote, in a small park next to the old manse. Ironically, Irvine is close to the site of the old Nobel ICI explosives plant at Ardeer, which from the mid-1930s become the centre of gunpowder manufacture in Britain; and was the last site in Britain to manufacture gunpowder.
An unusual example exists in East Ayrshire, Scotland at Knockinglaw (now Knockenlaw mound); it is shown on the 1896 OS and still exists in very poor condition as of 2007 [update] . It is near Little Onthank on the outskirts of Kilmarnock, and was originally a tumulus in which urns had been found. [39] A powder magazine was built into this large pre-existing earth mound at an unknown date and the site is now in a housing scheme.
Gunpowder magazines survive at the following locations, among others:
The Board of Ordnance was a British government body. Established in the Tudor period, it had its headquarters in the Tower of London. Its primary responsibilities were 'to act as custodian of the lands, depots and forts required for the defence of the realm and its overseas possessions, and as the supplier of munitions and equipment to both the Army and the Navy'. The Board also maintained and directed the Artillery and Engineer corps, which it founded in the 18th century. By the 19th century, the Board of Ordnance was second in size only to HM Treasury among government departments. The Board lasted until 1855, at which point it was disbanded.
The Royal Arsenal, Woolwich is an establishment on the south bank of the River Thames in Woolwich in south-east London, England, that was used for the manufacture of armaments and ammunition, proofing, and explosives research for the British armed forces. It was originally known as the Woolwich Warren, having begun on land previously used as a domestic warren in the grounds of a mid-16th century Tudor house, Tower Place. Much of the initial history of the site is linked with that of the Office of Ordnance, which purchased the Warren in the late 17th century in order to expand an earlier base at Gun Wharf in Woolwich Dockyard.
Tilbury Fort, also known historically as the Thermitage Bulwark and the West Tilbury Blockhouse, is an artillery fort on the north bank of the River Thames in England. The earliest version of the fort, comprising a small blockhouse with artillery covering the river, was constructed by King Henry VIII to protect London against attack from France as part of his Device programme. It was reinforced during the 1588 Spanish Armada invasion scare, after which it was reinforced with earthwork bastion, and Parliamentary forces used it to help secure the capital during the English Civil War of the 1640s. Following naval raids during the Anglo-Dutch Wars, the fort was enlarged by Sir Bernard de Gomme from 1670 onwards to form a star-shaped defensive work, with angular bastions, water-filled moats and two lines of guns facing onto the river.
Purfleet-on-Thames is a town in the Thurrock unitary authority, Essex, England.
Fort Blockhouse is a former military establishment in Gosport, Hampshire, England, and the final version of a complicated site. At its greatest extent in the 19th century, the structure was part of a set of fortifications which encircled much of Gosport. It is surrounded on three sides by water and provides the best view of the entrance to Portsmouth Harbour. As HMS Dolphin, the fort was for most of the 20th century the home of the Royal Navy Submarine Service. It is unique in that it was built over five centuries from its original construction as a blockhouse in 1431 to the final addition of submarine base structures in the mid-1960s.
Fort Cumberland is a pentagonal artillery fortification erected to guard the entrance to Langstone Harbour, east of the Dockyard of Portsmouth on the south coast of England. It was sited to protect the Royal Navy Dockyard, by preventing enemy forces from landing in Langstone Harbour and attacking from the landward side. Fort Cumberland is widely recognised as the finest example of a bastion trace fort in England. It is a scheduled monument and a Grade II* listed building
Lower Upnor and Upper Upnor are two small villages in Medway, Kent, England. They are in the parish of Frindsbury Extra on the western bank of the River Medway. Today the two villages are mainly residential and a centre for small craft moored on the river, but Upnor Castle is a preserved monument, part of the river defences from the sixteenth century.
Goat Island is a heritage-listed island located in Port Jackson, in Sydney, New South Wales, Australia. Located northwest of the Sydney central business district, Goat Island is about 300m wide in a north/south direction and 180m long in an east/west direction; and covers an area of 5.4 hectares. Goat Island lies off the shores of the Sydney suburbs of Balmain and Millers Point, at the junction of Darling Harbour with the main channel of Sydney Harbour.
Tipner is a residential district of Portsmouth, located on the north western corner of Portsea Island in southern England. It includes a housing estate, built during the 1930s, that used to function as married quarters for the Royal Navy, a yachting club, allotments, a primary school, The Harbour special school, and indoor and outdoor rifle ranges. There is a nearby sports centre at Alexandra Park. Tipner is bounded to the north and west by the M275 motorway and Tipner Lake. To the south is Stamshaw.
Priddy's Hard is a former military installation in Gosport on the south coast of England, named for the original landowner and the firm beach found there.
Upnor Castle is an Elizabethan artillery fort located on the west bank of the River Medway in Kent. It is in the village of Upnor, opposite and a short distance downriver from the Chatham Dockyard, at one time a key naval facility. The fort was intended to protect both the dockyard and ships of the Royal Navy anchored in the Medway. It was constructed between 1559 and 1567 on the orders of Elizabeth I, during a period of tension with Spain and other European powers. The castle consists of a two-storeyed main building protected by a curtain wall and towers, with a triangular gun platform projecting into the river. It was garrisoned by about 80 men with a peak armament of around 20 cannon of various calibres.
Newington Armory is a heritage-listed former Royal Australian Navy armament depot, now used for tourism purposes, at Holker Street, Sydney Olympic Park, Cumberland Council, New South Wales, Australia. It was built from 1897 initially by the New South Wales Military Forces then by the Australian Army and later by the Royal Australian Navy. It is also known as Millennium Heritage Parklands Precinct, RAN Armament Depot Newington, Royal Australian Navy Armament Depot (RANAD), Newington Nature Reserve and Sydney Olympic Games site. The property is owned by the Sydney Olympic Park Authority. It was added to the New South Wales State Heritage Register on 14 January 2011.
Powder Magazine, Powder House, or Powderworks may refer to:
A Royal Naval Armament Depot (RNAD) is an armament depot dedicated to supplying the Royal Navy. They were sister depots of Royal Naval Cordite Factories, Royal Naval Torpedo and Royal Naval Mine Depots. The only current RNAD is RNAD Coulport, which is the UK Strategic Weapon Facility for the nuclear-armed Trident Missile System, with many others being retained as tri-service 'Defence Munitions' sites.
The Square Tower is one of the oldest parts of the fortifications of Portsmouth, England. It is a Grade I listed building.
Clifford's Fort was a defensive gun battery established near the mouth of the Tyne during the Anglo-Dutch Wars in the 17th century. It subsequently served as a submarine mining depot and survives today as a Scheduled Ancient Monument in the historic Fish Quay area of North Shields, Tyne and Wear, in North East England.
The Magazine Fort is a bastion fort and magazine located within the Phoenix Park, in Dublin, Ireland. Built in 1735, it was occupied by British Armed Forces until 1922 when it was turned over to the Irish Defence Forces after the Anglo-Irish Treaty. The Irish Army continued to operate the site as an ammunition store through the mid-20th century. It was fully demilitarised by the 1980s. The fort is now managed by the Office of Public Works. As of 2015, it was in a derelict state and not open to the public, however, some repairs were undertaken and the site partially opened for "limited guided tours" from 2016.
Chattenden and Lodge Hill Military Camps were British Army training camps in Chattenden and Hoo St Werburgh in Kent. They were built as ordnance depots and functioned as such through to the second half of the twentieth century.
The Naval Ordnance Stores Department, was a former department of the Admiralty responsible for the management of naval ordnance storage facilities and depots of the Royal Navy the department was managed by a Superintendent of Stores supported by various deputy and assistant superintendents's it existed from 1891 to 1918 when it was replaced by the Armament Supply Department.
John Peter Desmaretz was a British civil and military engineer. His projects included a new entrance to Shoreham-by-Sea's harbour (1753), powder and horse mills in Faversham (1755-1763) and for gun batteries at vulnerable points on the coasts of Kent and Sussex (1759). He also advised on modifications to Edward Gatton's plans for Ramsgate harbour (1749-1772).
