Surrey is a ceremonial county in South East England. It is bordered by Greater London to the north east, Kent to the east, East and West Sussex to the south, and Hampshire and Berkshire to the west. The largest settlement is Woking.
Guildford is a town in west Surrey, England, around 27 mi (43 km) southwest of central London. As of the 2011 census, the town has a population of about 77,000 and is the seat of the wider Borough of Guildford, which had around 143,650 inhabitants in mid-2019 est.. The name "Guildford" is thought to derive from a crossing of the River Wey, a tributary of the River Thames that flows through the town centre.
A moat is a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building, or town, historically to provide it with a preliminary line of defence. In some places moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental. They could also act as a sewer.
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere.
Reigate is a town in Surrey, England, around 19 mi (31 km) south of central London. The settlement is recorded in Domesday Book in 1086 as Cherchefelle and first appears with its modern name in the 1190s. The earliest archaeological evidence for human activity is from the Paleolithic and Neolithic, and during the Roman period, tile-making took place to the north east of the modern centre.
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.
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.
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.
Fort Halstead was 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.
The fortifications of London are extensive and mostly well maintained, though many of the City of London's fortifications and defences were dismantled in the 17th and 18th century. Many of those that remain are tourist attractions, most notably the Tower of London.
Betsom's Hill is a hill on the North Downs, and the highest point in the county of Kent at 251 metres (823 ft). Situated between Westerham and Tatsfield, at the western edge of the county, it lies close to where the A233 crosses the Downs en route to Biggin Hill. This is the highest part of the North Downs, with Botley Hill the highest point, nearby to the west. The hill lies at the western end of the Kent Downs, an area of outstanding natural beauty.
Henley Fort is a Victorian fort near Guildford, Surrey, at the eastern end of the 'Hog's Back' ridge.
The Lines of Communication were English Civil War fortifications commissioned by Parliament and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. It acted to supplement the inner defences provided by Roman and medieval wall in the City of London which underwent repairs and maintenance at this time.
Pewley Hill is a hill, and a street so named, near Guildford in England. It links to the open space at Pewley Down and was used as the site of a semaphore station and a defensive fort in the nineteenth century. In the late 19th and early 20th centuries much of the land was built upon.
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.
Mersea Fort, also known as Cudmore Grove Blockhouse, was an artillery fort established by Henry VIII on the East Mersea coast in 1543. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the River Colne that led to the town of Colchester. It was triangular in shape, with earthwork walls and three bastions to hold artillery. It was demobilised in 1552, but was brought back into use several times over the next century and saw service during the Second English Civil War of 1648. The fort hosted an admiralty court to oversea the local oyster trade, until the dilapidation of the site forced the court to move to the Moot Hall in Colchester in the middle of the 18th century. A new gun battery was built at the fort during the Napoleonic Wars, but the fortification then fell into decline and was extensively damaged by the construction of a sea wall along the coast. The remains of the earthworks were excavated by archaeologists between 2002 and 2003.
A polygonal fort is a type of fortification originating in France in the late 18th century and fully developed in Germany in the first half of the 19th century. Unlike earlier forts, polygonal forts had no bastions, which had proved to be vulnerable. As part of ring fortresses, polygonal forts were generally arranged in a ring around the place they were intended to protect, so that each fort could support its neighbours. The concept of the polygonal fort proved to be adaptable to improvements in the artillery which might be used against them, and they continued to be built and rebuilt well into the 20th century.
