Fort Southwick is one of the forts found on Portsdown Hill, which overlooks the naval base of Portsmouth in the county of Hampshire, England.
Fort Southwick was built to defend the landward approaches to the naval base on the recommendation of the Royal Commission on the Defence of the United Kingdom which reported in 1860.
It is the highest fort on the hill, and holds the water storage tanks for the other forts, supplying them via a brick lined aqueduct. Construction was started in 1861 and completed by 1870. It was designed to house a large complement of men (about 220) in a crescent-shaped barrack block. Its north projection has one full caponier to defend the dry ditch, and has two smaller demi-caponiers at the corners. A small musketry gallery crosses the ditch at the south-west angle to cover a minor branch of the ditch. Mortar batteries of five mortars each can be found set into the rampart behind the demi-caponiers.
In 1893 the fort was armed with a total of 23 guns:
A central spiral staircase from the surface gives access to four main tunnels running radially outward from it at uneven angles. These tunnels lead to the barrack block and caponiers, and past the magazine.
During the Second World War, Underground Headquarters of UGHQ, the communications "nerve centre" for Operation Overlord, was in a secret network of tunnels excavated between February and December 1942 by 172 Tunnelling Company of the Royal Engineers 100 ft (30 m) underneath Fort Southwick, well out of reach of any bombs of the era. The call sign of this base was 'MIN'.
Although disarmed in 1906, the fort was retained by the military as a barracks, and also used to train soldiers how to capture and hold a fort. It became a demobilisation centre for three years after the First World War. The fort was part of the Admiralty Research Establishment until 2002, when all operational use of the fort ceased. It was sold by the Ministry of Defence in July 2003 to the "Fort Southwick Company Limited", who intend to convert the barrack block into luxury apartments. [1]
It has been a Grade I Listed Building since 1987. [2] [3]
Portsdown Hill is a long chalk ridge in Hampshire, England. The highest point of the hill lies within Fort Southwick at 131m above sea level. The ridge offers good views to the south over Portsmouth, the Solent, Hayling Island and Gosport, with the Isle of Wight beyond. The hill is on the mainland, just to the north of Ports Creek, which separates the mainland from Portsea Island, on which lies the main part of the city of Portsmouth, one of the United Kingdom's main naval bases. To the north lies the Forest of Bere, with the South Downs visible in the distance. Butser Hill can be seen on a clear day. The hill is formed from an inlier of chalk which has been brought to the surface by an east–west upfold of the local strata known as the Portsdown Anticline.
Newhaven Fort is a Palmerston fort built in the 19th century to defend the harbour at Newhaven, on the south coast of England. It was the largest defence work ever built in Sussex and is now open as a museum.
Shoreham Redoubt is a historical military defensive structure and scheduled monument at the entrance to Shoreham harbour, at the mouth of the River Adur in West Sussex, England. It was planned in the 1850s during a period of political alarm in the United Kingdom. Construction of the fort was completed in June 1857 at a cost of £11,685. The design is similar to that of Littlehampton Fort, which had been built in 1854.
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
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.
New Tavern Fort is an historic artillery fort in Gravesend, Kent. Dating mostly from the 18th and 19th centuries, it is an unusually well-preserved example of an 18th-century fortification and remained in use for defensive purposes until the Second World War. It was built during the American War of Independence to guard the Thames against French and Spanish raiders operating in support of the newly formed United States of America. It was redesigned and rebuilt in the mid-19th century to defend against a new generation of iron-clad French warships.
Crownhill Fort is a Royal Commission Fort built in the 1860s in Crownhill as part of Lord Palmerston's ring of land defences for Plymouth.

The Fort is open to the public on the last Friday of each month and hosts tours for local schools and societies at other times.
The Needles Batteries are two military batteries built above the Needles stacks to guard the West end of the Solent. The field of fire was from approximately West South West clockwise to Northeast and they were designed to defend against enemy ships.
Fort Gilkicker is a historic Palmerston fort built at the eastern end of Stokes Bay, Gosport, Hampshire England to dominate the key anchorage of Spithead. It was erected between 1863 and 1871 as a semi-circular arc with 22 casemates, to be armed with five twelve-inch guns, seventeen ten-inch guns and five nine-inch guns. The actual installed armament rather differed from this. In 1902 the RML guns were replaced by two 9.2-inch and two six-inch BL guns, and before the First World War the walls were further strengthened with substantial earthwork embankments. The fort was disarmed in 1956 and used for storage until 1999, and is currently in a state of disrepair.
Fort Widley is one of the forts built on top of Portsdown Hill between 1860 and 1868 on the recommendation of the Royal Commission on the Defence of the United Kingdom. It was designed, along with the other Palmerston Forts atop Portsdown, to protect Portsmouth from attack from the rear.
Fort Fareham is one of the Palmerston Forts, in Fareham, England. After the Gosport Advanced Line of Fort Brockhurst, Fort Elson, Fort Rowner, Fort Grange and Fort Gomer had been approved by the Royal Commission on the Defence of the United Kingdom a decision was made to build an outer line of three more forts two miles in advance of the Gosport Advanced Line. Of these three projected forts only Fort Fareham was built due to the need to cut costs. It acted as a hinge between the forts on Portsdown Hill and those of the Gosport Advanced Line, filling the gap at Fareham. It has been a Grade II Listed Building since 1976.
Fort Nelson, in the civil parish of Boarhunt in the English county of Hampshire, is one of five defensive forts built on the summit of Portsdown Hill in the 1860s, overlooking the important naval base of Portsmouth.

Tregantle Fort in south east Cornwall is one of several forts surrounding Plymouth that were built as a result of a decision in Lord Palmerston's premiership to deter the French from attacking naval bases on the Channel coast.
Fort Gomer was one of the Palmerston Forts, in Gosport, England, the southernmost and first-built Polygonal fort in the defence line to the west of Gosport. It was located on land immediately to the west of the present Gomer Lane. Fort Gomer was the most southerly fort in the line of five which formed part of the ‘Sea Front and Spithead Defences’, Inner Line, Land Front, Left Flank. This line of forts was later known as the Gomer-Elson Line or 'Gosport Advanced Line' This consisted of, from south to north, Fort Gomer, Fort Grange, Fort Rowner, Fort Brockhurst and Fort Elson. An inscription above the main entrance through the barrack block read `Erected AD 1853’. The fort was almost complete before work began on Fort Elson in 1855. The estimated cost of Fort Gomer was £92,000 in 1869.
