Crosshaven is a village in County Cork, Ireland. It is located in lower Cork Harbour at the mouth of the River Owenabue, across from Currabinny Wood. Originally a fishing village, from the 19th century, the economy of the area became more reliant on a growing tourism industry.
Grain Fort is a former artillery fort located just east of the village of Grain, Kent. It was constructed in the 1860s to defend the confluence of the Rivers Medway and Thames during a period of tension with France. The fort's location enabled its guns to support the nearby Grain Tower and Garrison Point Fort at Sheerness on the other side of the Medway. It was repeatedly altered and its guns upgraded at various points in its history, before being decommissioned in 1956 when the UK abolished its coastal defence programme. It was subsequently demolished. The remnants of the fort are still visible and have been incorporated into a coastal park.
Garrison Point Fort is a former artillery fort situated at the end of the Garrison Point peninsula at Sheerness on the Isle of Sheppey in Kent. Built in the 1860s in response to concerns about a possible French invasion, it was the last in a series of artillery batteries that had existed on the site since the mid-16th century. The fort's position enabled it to guard the strategic point where the River Medway meets the Thames. It is a rare example of a two-tiered casemated fort – one of only two of that era in the country – with a design that is otherwise similar to that of several of the other forts along the lower Thames. It remained operational until 1956 and is now used by the Sheerness Docks as a port installation.
Cork Harbour is a natural harbour and river estuary at the mouth of the River Lee in County Cork, Ireland. It is one of several which lay claim to the title of "second largest natural harbour in the world by navigational area". Other contenders include Halifax Harbour in Canada, Trincomalee Harbour in Sri Lanka and Poole Harbour in England.
The Royal Commission on the Defence of the United Kingdom was a committee formed in 1859 to enquire into the ability of the United Kingdom to defend itself against an attempted invasion by a foreign power, and to advise the British Government on the remedial action required. The appointment of the Commission had been prompted by public concern about the growing military and naval power of the French Empire and was instigated by the Prime Minister, Henry Temple, 3rd Viscount Palmerston, who came to be closely associated with the project. In the following year, the Commission's report recommended a huge programme of fortification to defend the country's arsenals and naval bases. Many of the recommendations were acted upon; however, the great expense, the length of time taken to complete the various works and their perceived usefulness were all subjects of critical political, press and public debate.
The Brennan torpedo was a torpedo patented by Irish-born Australian inventor Louis Brennan in 1877. It was propelled by two contra-rotating propellers that were spun by rapidly pulling out wires from drums wound inside the torpedo. Differential speed on the wires connected to the shore station allowed the torpedo to be guided to its target, up to 2,000 yards (1,800 m) away, at speeds of up to 27 knots (31 mph).
Spike Island is an island of 103 acres (42 ha) in Cork Harbour, Ireland. Originally the site of a monastic settlement, the island is dominated by an 18th-century bastion fort now named Fort Mitchel.
Charles Fort is a trace italienne fortification, a bastion fort with one section of the outer wall built in star fashion. It is located at the southern end of the village of Summer Cove, on Kinsale harbour, County Cork, Ireland. First completed in 1682, Charles Fort was sometimes historically referred to as the "new fort" - to contrast with James' Fort which had been built on the other side of Kinsale harbour before 1607. The fort is now operated as a heritage tourism site by the Heritage Ireland arm of the Office of Public Works.
Cliffe Fort is a disused artillery fort built in the 1860s to guard the entrance to the Thames from seaborne attack. Constructed during a period of tension with France, it stands on the south bank of the river at the entrance to Cliffe Creek in the Cliffe marshes on the Hoo Peninsula in North Kent, England. Its location on marshy ground caused problems from the start and necessitated changes to its design after the structure begin to crack and subside during construction. The fort was equipped with a variety of large-calibre artillery guns which were intended to support two other nearby Thamesside forts. A launcher for the Brennan torpedo—which has been described as the world's first practical guided missile—was installed there at the end of the 19th century but was only in active use for a few years.
Coastal fortifications were constructed in New Zealand in two main waves: around 1885 as a response to fears of an attack by Russia, and in World War II due to fears of invasion by the Japanese.
Coastal defenceand coastal fortification are measures taken to provide protection against military attack at or near a coastline, for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries". Coastal defence weapons throughout history were heavy naval guns or weapons based on them, often supplemented by lighter weapons. In the late 19th century separate batteries of coastal artillery replaced forts in some countries; in some areas these became widely separated geographically through the mid-20th century as weapon ranges increased. The amount of landward defence provided began to vary by country from the late 19th century; by 1900 new US forts almost totally neglected these defences. Booms were also usually part of a protected harbor's defences. In the middle 19th century underwater minefields and later controlled mines were often used, or stored in peacetime to be available in wartime. With the rise of the submarine threat at the beginning of the 20th century, anti-submarine nets were used extensively, usually added to boom defences, with major warships often being equipped with them through early World War I. In World War I railway artillery emerged and soon became part of coastal artillery in some countries; with railway artillery in coast defence some type of revolving mount had to be provided to allow tracking of fast-moving targets.
Fort Victoria is a disused British Army fort, built to house coastal artillery atop Retreat Hill, within St. George's Garrison, at the North-East of St. George's Island, in the British colony of Bermuda.
Fort Davis, is a coastal defence fortification close to Whitegate, County Cork, Ireland. Together with similar structures at Fort Mitchel, Fort Camden (Crosshaven), and Templebreedy Battery, the fort was built to defend the mouth of Cork Harbour. Though used as a fortification from the early 17th century, the current structures of the 74-acre site date primarily from the 1860s. Originally named Fort Carlisle and operated by the British Armed Forces, the fort was handed-over to the Irish Defence Forces in 1938, and renamed Fort Davis. The facility is owned by the Department of Defence, and is used as a military training site with no public access.
Fort Templebreedy, also known as Templebreedy Battery, was a coastal defence fortification close to Crosshaven, in County Cork, Ireland. Supplementing a number of earlier structures at Fort Camden and Fort Davis, the site was developed between 1904 and 1909 to defend the mouth of Cork Harbour. Used as a coastal artillery position until the 1940s, and as a military training camp until the late 20th century, many of the structures of the 37-acre site were dismantled over time, and part of the complex used as a pitch and putt course. In 2009, Cork County Council added the site to a proposed list of protected structures – though as of 2020 it remains in the ownership of the Department of Defence.
Cove Fort is a small bastioned land battery to the east of Cobh in County Cork, Ireland. Built as a coastal defence fortification in 1743, on instruction of the then Vice-Admiral of the Coast, it replaced a number of temporary coastal artillery batteries which defended Cork Harbour.
Dummy Battery, originally known as Grain Battery, is a disused fortified gun battery located about 1 kilometre (0.62 mi) south of the village of Grain, Kent at the confluence of the Rivers Thames and Medway. Completed in 1865, it supported two nearby coast artillery batteries at Grain Fort and Grain Wing Battery, a short distance to the north. The battery's arc of fire overlapped with Grain Tower just offshore and with Garrison Point Fort on the Isle of Sheppey across the other side of the Medway. It consisted of an earthwork with a concrete core supporting several gun emplacements with magazines below. It appears to have gone out of service as a battery by the time of the First World War, though it briefly took on a role in anti-aircraft defence. It was subsequently abandoned and was severely damaged by demolitions and the removal of its earthworks, leaving only the substantial remains of its concrete core standing today.
West Blockhouse Fort is a mid-19th century coastal artillery fort at West Blockhouse Point, a rocky headland near Dale, Pembrokeshire, to the west of Milford Haven in Wales.
Forder Battery is a former 19th-century fort, built as a result of the Royal Commission on National Defence 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 landward approaches to the north east of Plymouth, as an element of the plan for the defence of the Royal Naval Dockyard at Devonport.
