The fortifications of Plymouth in Devon are extensive due to its natural harbour, its commanding position on the Western Approaches and its role as the United Kingdom's largest naval base. The first medieval defences were built to defend Sutton Harbour on the eastern side of Plymouth Sound at the mouth of the River Plym, but by the 18th century, naval activity had begun to shift westward to Devonport at the mouth of the River Tamar. During the Victorian era, advances in military technology led to a huge programme of fortification encompassing the whole of Plymouth Sound together with the overland approaches. Many of these works remained in military use well into the 20th century.
At the time of the Norman Conquest, Plymouth was a tiny settlement at Sutton Harbour, but in 1295 and 1357, royal expeditions to France had used Plymouth as a final gathering place before making the crossing. In 1377, a murage grant was received to fund its fortification, although what form these works took is unknown.
Following a French raid on Plymouth in August 1403, King Henry IV ordered the prior of Plympton and the abbot of Tavistock to further fortify the town with walls and towers. The eventual result of this was a castle with four towers overlooking the town and harbour, which seems to have been largely funded by the townspeople and was under the control of Plymouth's mayor and aldermen. [1] Only a small section of the castle fabric survives, located in Lambhay Street, at the head of a flight of stairs leading down to the Mayflower Steps on the quayside. [2]
Closely associated with the castle was a fortification right at the mouth of Sutton Harbour which gives its name to the present Barbican district. From depictions on Renaissance maps, it apparently consisted of a fortified jetty from which the harbour entrance could be "chained over when the need requireth". [3]
During the early Tudor period, six blockhouses were constructed at various points around Plymouth Sound. These were small artillery towers intended to command the stretch of water immediately in front of them. [4]
In 1590, Sir Francis Drake was appointed to improve the defences of Plymouth. After setting up some temporary artillery batteries on the Hoe and on St Anthony's Island, (later known as Drake's Island), he requested the funds to build a permanent fort on the Hoe and in 1592, Queen Elizabeth I imposed a local tax on pilchards for the purpose. Construction of the fort, later called Drake's Fort , continued until 1596 after Drake's death. [6] The northern landward side of the fort was protected by two bastions and it enclosed the previously established batteries on the Hoe and also the Fisher's Nose Blockhouse. A further blockhouse called Queen Elizabeth's Tower was built a short distance to the west of Fisher's Nose. [7] In July 1602 an Italian military engineer called "Frederick Genebelli" or Federigo Giambelli was appointed to supervise works at Plymouth fort. [8]
During the English Civil War, Plymouth declared for Parliament while much of the rest of Devon and Cornwall was a stronghold of the Royalists. Accordingly, the town was besieged by Royalist forces between 1643 and 1646. The existing fortifications only protected Plymouth from the sea, and so a ditch and earthen rampart were hastily built around the town, with a further line of triangular redoubts on high ground to the north, stretching from Lipson in the east, across North Hill to Stonehouse in the west. The Royalists built their own line of redoubts facing them, but lacked the heavy guns needed for a breakthrough. The besiegers were able to build a battery on the headland later called Mount Batten, effectively preventing ships from entering Sutton Pool and forcing the Plymothians to use the harbour at Millbay instead. [9]
Built in 1652, Mount Batten Tower is a 30-foot high circular artillery fort dominating the Cattewater from the south, opposite Fisher's Nose.
The Royal Citadel was built from 1665 to the design of Sir Bernard de Gomme. It is a bastion fort at the eastern end of the Hoe, constructed over the site of Drake's Fort. It is still in military use, being the base of 29 Commando Regiment of the Royal Artillery, although guided tours are available during the summer. [7]
To the east of the entrance to Sutton Pool, an open artillery battery was completed in 1667; [10] it was later named after Queen Anne who reigned from 1702 to 1714. The site of the battery is now a marina.
In 1690, work had started on a new Royal Dockyard on the Hamoaze, initially called Plymouth Dock but later renamed Devonport. In 1701, new earthen batteries were built to protect dockyard at Devil's Point (Stonehouse), Drake's Island and Cawsand Bay.
When the Seven Years' War brought conflict with France and Spain, it was decided to protect the dockyard from landward attack by means of a ditch and earthen rampart, known as the Dock Lines or later the Devonport Lines. The total length was about 2,000 yards (1,800 metres) and included four bastions and two gateways, a third gate was added at the end of the century to give access to the Torpoint Ferry. The lines were supported in the rear by a series of defensible barracks, each provided with a rampart and bastions. [11] A survey in 1805 shows 130 guns mounted on the lines and they were completely rebuilt from 1810 to 1816 with a stone faced rampart and a deeper ditch. [12] The lines were progressively abandoned and redeveloped in the second half of the 19th century. [11]
About 1,000 yards (900 metres) forward of the Dock Lines, a rectangular redoubt was built at Stoke on top of Mount Pleasant. [13] It was an earthwork with stone facings, defended by a ditch and drawbridge. The remains of the redoubt can be seen in Mount Pleasant Park. [14]
The American War of Independence again brought a threat from France and Spain who had entered the war as allies of the Thirteen Colonies. There was a perceived weakness in Plymouth's defences on the Cornish (western) side of Plymouth Sound, and although simple batteries had been built at Barnpool, Kingsand. Cawsand and a redoubt at Cremyll, it was thought that an attacking force could establish themselves on the ridge of high ground near the village of Maker which overlooked both the Sound and the dockyard. In August 1779, a fleet of French and Spanish ships anchored off Cawsand Bay but withdrew soon afterwards; regular and militia troops camped on Maker Heights for the following three summers and constructed a line of five earthen redoubts along the ridge under the direction of Lieutenant-Colonel Dixon. During the French Revolutionary Wars, redoubts Number 4 and 5 were rebuilt with stone revetments and a sixth stone redoubt was built at Empacombe in 1807. [15]
The Palmerston Forts were built as part of an arms race with France under Napoleon III and a perceived threat of invasion. Although work on some of the forts around Plymouth started in the late 1850s, most were based on the recommendations of the Royal Commission on the Defence of the United Kingdom, which was established by Lord Palmerston in 1859 and reported in the following year. The forts which were actually constructed provided two lines of coastal artillery forts to defend the seaward approaches to Plymouth and the dockyard at Devonport, while a further semi-circle of forts defended the overland approaches. Note that some works are defined as "forts" and some as "batteries" without any clear distinction between the two appellations.
Following the 1859 Royal Commission, the defences of Britain's dockyards were reviewed at intervals during the late 19th and early 20th centuries. As a result of improved weapons and changes in tactical doctrine, a number of new fortified batteries were constructed, while older ones were either modernised or disarmed.
Plymouth Sound, or locally just The Sound, is a deep inlet or sound in the English Channel near Plymouth in England.
Citadel Hill is a hill that is a National Historic Site in Halifax, Nova Scotia, Canada. Four fortifications have been constructed on Citadel Hill since the city was founded by the English in 1749, and were referred to as Fort George—but only the third fort was officially named Fort George. According to General Orders of October 20, 1798, it was named after King George III. The first two and the fourth and current fort, were officially called the Halifax Citadel. The last is a concrete star fort.
Devonport, formerly named Plymouth Dock or just Dock, is a district of Plymouth in the English county of Devon, although it was, at one time, the more important settlement. It became a county borough in 1889. Devonport was originally one of the "Three Towns" ; these merged in 1914 to form what would become in 1928 the City of Plymouth. It is represented in the Parliament of the United Kingdom as part of the Plymouth Sutton and Devonport constituency. Its elected Member of Parliament (MP) is Luke Pollard, who is a member of the Labour Party. The population of the ward at the 2011 census was 14,788.
The fortifications of Portsmouth are extensive due to its strategic position on the English Channel and role as home to the Royal Navy. For this reason, Portsmouth was, by the 19th century, one of the most fortified cities in the world. The fortifications have evolved over the centuries in response to changes in tactics and technology and the area defended has increased. While the first defences focused on Portsmouth harbour, in step with the fortifications of Gosport, later defensive structures protected the whole of Portsea Island and an increasing distance inland. At the same time, the fortifications of Portsmouth and Gosport became part of the wider fortifications of the Solent. Old Portsmouth, on the southwest corner of Portsea Island, has been walled for much of its history.
Cawsand and Kingsand are twin villages in southeast Cornwall, England, United Kingdom. The village is situated on the Rame Peninsula and is in the parish of Maker-with-Rame.
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force or cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt.
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. 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. Coastal fortification was abolished nationally in 1956, and the fort has not been used in a military capacity since 2021.
The Western Heights of Dover are one of the most impressive fortifications in Britain. They comprise a series of forts, strong points and ditches, designed to protect the country from invasion. They were created in the 18th and 19th centuries to augment the existing defences and protect the key port of Dover from both seaward and landward attack; by the start of the 20th century Dover Western Heights was collectively reputed to be the 'strongest and most elaborate' fortification in the country. The Army finally withdrew from the Heights in 1956–61; they are now a local nature reserve.
Beacon Hill Battery is a late-19th and 20th century coastal fortification that was built to defend the port of Harwich, Essex. It is a scheduled ancient monument.
The Royal Citadel in Plymouth, Devon, England, was built in the late 1660s to the design of Sir Bernard de Gomme. It is at the eastern end of Plymouth Hoe overlooking Plymouth Sound, and encompasses the site of the earlier fort that had been built in the time of Sir Francis Drake. The citadel site is a Scheduled Monument and many of the buildings within are Grade II Listed.
Fort Picklecombe stands on the extreme south eastern coast of Cornwall, a couple of miles west of the city of Plymouth. The fort has been a residential complex since the early 1970s but has a history dating back 150 years.
The Rame Peninsula is a peninsula in south-east Cornwall. It is surrounded by the English Channel to the south, Plymouth Sound to the east, the Hamoaze to the northeast and the estuary of the River Lynher to the north-west. On a clear day, the Atlantic Ocean can be seen from advantageous points from Rame Head. The largest settlement is Torpoint, which is on the eastern coast, facing Devonport in Plymouth, Devon.
Maker is a village between Cawsand and Rame Head, Rame Peninsula, Cornwall, England, United Kingdom.
The History of Plymouth in Devon, England, extends back to the Bronze Age, when the first settlement began at Mount Batten a peninsula in Plymouth Sound facing onto the English Channel. It continued as both a fishing and continental tin trading port through the late Iron Age into the Early Medieval period, until the more prosperous Saxon settlement of Sutton, later renamed Plymouth, surpassed it. With its natural harbour and open access to the Atlantic, the town found wealth and a national strategic importance during the establishment of British naval dominance in the colonisation of the New World. In 1620 the Pilgrim Fathers departed from Plymouth to establish the second English colony in America. During the English Civil War the town was besieged between 1642 and 1646 by the Royalists, but after the Restoration a Dockyard was established in the nearby town of Devonport. Throughout the Industrial Revolution Plymouth grew as a major mercantile shipping industry, including imports and passengers from the US, whilst Devonport grew as a naval base and ship construction town, building battleships for the Royal Navy – which later led to its partial destruction during World War II in a series of air-raids known as the Plymouth Blitz. After the war was over, the city centre was completely rebuilt to a new plan.
The Twydall Profile was a style of fortification used in British and Imperial polygonal forts at the end of the 19th century. The sloping earthworks employed in the Twydall Profile were intended to be quick and inexpensive to construct and to be effective in the face of the more powerful artillery and high explosive ammunition being introduced at that time. The name comes from the village of Twydall in Kent, where the first forts of this type were built.
The fortifications of Malta consist of a number of walled cities, citadels, forts, towers, batteries, redoubts, entrenchments and pillboxes. The fortifications were built over hundreds of years, from around 1450 BC to the mid-20th century, and they are a result of the Maltese islands' strategic position and natural harbours, which have made them very desirable for various powers.
The Western King's Redoubt is an 18th and 19th-century artillery battery in Plymouth, Devonshire, England, upgraded as a result of the Royal Commission on the Defence of the United Kingdom of 1859. Part of an extensive scheme known as Palmerston Forts, after the prime minister who championed the scheme, it was built to defend the seaward approaches to the Hamoaze, as an element of the plan for the defence of the Royal Naval Dockyard at Devonport.
Grenville Battery is a former coastal artillery battery, built to defend the Royal Naval Dockyard at Devonport.
Raleigh Battery is a former coastal artillery battery, built to defend the Royal Naval Dockyard at Devonport.
