WFort Halstead is a research site of Dstl, an executive agency of the UK Ministry of Defence. It is situated on the crest of the Kentish North Downs, overlooking the town of Sevenoaks, southeast of London. Originally constructed in 1892 as part of a ring of fortresses around London, Fort Halstead was to be staffed by volunteers in the event of a crisis.
WLittlehampton Redoubt, usually known as Littlehampton Fort, was built in 1854 to protect the entrance to the River Arun at Littlehampton on the south coast of England, against possible attack by the French under the Emperor Napoleon III. There had been a previous battery on the east bank of the river, but the new fort was built on the west bank. It consisted of a platform from which cannon could sweep the harbour mouth, with a barracks behind and a surrounding defensive ditch and wall. The fort was an innovative military structure, incorporating the new feature of a Carnot wall. Its active use as a fort was short at only about 20 years, owing to technical changes in armaments, but it was a precursor of the later Palmerston Forts and therefore is NOT the First Palmerston Fort as has been alleged. The Palmerston Forts were built after the 1860 commission. Littlehampton Fort is now in a ruinous and overgrown state but largely protected by the Ivy that now grows over the walls.
WFort Perch Rock is a former defence installation situated at the mouth of Liverpool Bay in New Brighton.

WShoreham 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.
WTilbury 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.
WThe Verne High Angle Battery is a former 19th-century gun battery on the Isle of Portland in Dorset, England. Situated close to the Verne Citadel, the battery is Grade II Listed, and forms part of the citadel's scheduled monument status. The battery has become a tourist attraction, while the battery's tunnels are often referred to by their local name 'Ghost Tunnels'.
WFort Victoria is a former military fort on the Isle of Wight, England, built to guard the Solent. The earliest fort on the site was a coastal fort known as Sharpenode Bulwark built in 1545–1547 by Henry VIII, but these defences had fallen into disrepair by the 17th century. Fort Victoria was built in the 1850s. It was a brick-built triangular fort with two seaward batteries meeting at a right angle. It remained in use until 1962. Parts of the fort were subsequently demolished; areas of the fort that were preserved have become part of Fort Victoria Country Park.
