List of Device Forts

The Device Forts, also known as Henrician castles and blockhouses, were a series of artillery fortifications built to defend the coast of England and Wales by Henry VIII.[2][lower-alpha 1] They ranged from large stone castles, to small blockhouses and earthwork bulwarks.[4] Armed with artillery, the forts were intended to be used against enemy ships before they could land forces or attack vessels lying in harbour.[5] The castles were commanded by captains appointed by the Crown, overseeing small garrisons of professional gunners and soldiers, who would be supplemented by local militia in an emergency.[6] The Device programme was hugely expensive, costing a total of £376,000, much of it raised from the proceeds of the Dissolution of the Monasteries.[7][lower-alpha 2]

The fate of the Device Forts over the coming years varied.[9] Some of the defences were left to deteriorate and were decommissioned only a few years after their construction.[10] Others were kept in service and used during the English Civil War, the Anglo-Dutch Wars, the Napoleonic Wars and, upgraded with more modern artillery and defences, throughout the 19th century.[11] By 1900, however, developments in guns and armour had made most of the Device Forts that remained in service simply too small to be practical in modern coastal defence.[12] Despite being brought back into use during the Second World War, by the 1950s those fortifications still in use were considered redundant and finally decommissioned.[13] Coastal erosion over the centuries had extensively damaged or completely destroyed some sites, but others have been restored and opened to the public as tourist attractions.[14]

Brightlingsea Blockhouse Brightlingsea
51.805412°N 1.010532°E / 51.805412; 1.010532 (Brightlingsea Blockhouse)
TM076161		 1543 River Colne N/A The blockhouse was an earthwork fort with a garrison of two officers and up to six men, which operated in partnership with St Osyth Blockhouse. It was decommissioned in 1552 and the site has since been lost, probably due to coastal erosion.
Brownsea Castle Brownsea Island
50.68834°N 1.95826°W / 50.68834; -1.95826 (Brownsea Castle)
SZ029876		 1545–47 Poole Harbour No The castle comprised a stone blockhouse with an adjacent, hexagonal gun platform, garrisoned by the local town with six soldiers and armed with eight artillery pieces. It was occupied by Parliament during the English Civil War, and was turned into a country house during the 18th century. It is now a corporate hotel for the John Lewis Partnership.[15]
Calshot Castle Calshot Spit
50.82°N 1.3075°W / 50.82; -1.3075 (Calshot Castle)
SU488024		 1539–40 Southampton Water Yes The castle had a keep at its centre, surrounded by a curtain wall and a moat. Initially heavily armed, it had a garrison of 16 men and as many as 36 artillery guns. The castle became a base for seaplanes in 1913, and, as RAF Calshot, remained active until its closure in 1961. After a short period of use by the coastguard, the castle was opened to the public by English Heritage in the 1980s.[16]
Camber Castle Rye
50.93305°N 0.73248°E / 50.93305; 0.73248 (CamberCastle)
TQ919184		 1513–43 Camber anchorage Yes The castle was rebuilt on the site of a previous tower in 1539, and expanded further from 1542 to 1543. The result was a large, concentric fort, with a central keep, surrounded by five circular bastions, built from stone and brick. It may have seen service in 1545 when a French fleet attacked the coast. The coastline receded, eventually placing it well in-land and the castle was closed in 1637.[17]
Deal Castle Deal
51.21854°N 1.4039°E / 51.21854; 1.4039 (Deal Castle)
TR376521		 1539-40 The Downs Yes The castle comprised a keep with six inner and outer bastions, and had sixty-six firing positions for artillery. During the Second English Civil War, it was seized by pro-Royalist insurgents and retaken by Parliamentary forces only after several months' fighting. Deal was adapted during the 18th and 19th centuries to form a private house for the castle's captain and was decommissioned in 1904. It was restored by the government during the 1950s as a tourist attraction.[18]

SZ511965		 1539–42 Cowes Harbour and the River Medina N/A The castle probably comprised a circular bastion and a square tower. It was abandoned around 1546-47 and fell into ruin. Nothing survives of the site, which was probably finally destroyed by coastal erosion.[21]

TQ691761		 1539–41 River Thames N/A The blockhouse was probably D-shaped, with a circular bastion facing the river and additional battery positions on both sides of the main defences, built using stone and timber taken from St Margaret's Chantry. The guns were removed in 1553 and it had probably fallen out of use by 1588. Coalhouse Fort was later built just inshore from the blockhouse, which may still survive under the Thames mud.[22]
Gravesend Blockhouse Gravesend
51.44463°N 0.37277°E / 51.44463; 0.37277 (Gravesend Blockhouse)
TQ649744		 1539 River Thames No The blockhouse was probably D-shaped, two storeys tall, with a circular bastion facing the river. There were lines of gun positions on both sides of the main defences. It was repaired in 1588 and 1667 due to the threat of Spanish and Dutch attack. The blockhouse was demolished in 1844.[23]
Great Turf Bulwark Deal
51.232089°N 1.4020357°E / 51.232089; 1.4020357 (Great Turf Bulwark)
TR376536[24]		 1540 The Downs N/A The bulwark comprised an earthwork defence, forming part of a chain between Sandown and Walmer Castle, linked by a trench or a covered way.

The town took over responsibility for these defences in 1553, which were used to imprison Catholic recusants, and saw military service during the English Civil War. The buildings were incorporated into a larger fortification called the Citadel in the 1680s and were demolished with it in 1864.[30]
Hurst Castle Hurst Spit
50.70644°N 1.55117°W / 50.70644; -1.55117 (Hurst Castle)

It was modernised to hold heavier guns at the start of the 19th century and during the 1850s. Two long wings for massive 12.5 inch, 38 ton (317 mm, 39,000 kg) rifled muzzle-loading guns were added in the 1860s. It was decommissioned in 1956, and is now owned by English Heritage.[31]

TM284318		 1540 Harwich N/A An earthwork fort with a garrison of two officers and up to six men, positioned on the shore. Plans were made for a replacement stone blockhouse, similar to Southsea Castle, in 1543 but the work was not carried out. It was decommissioned in 1552. Further plans were made for a bulwark at the site in 1588, but it is unclear what work, if any, was carried out. Landguard Fort was later built on the point.[32]

TM071151		 1543 River Colne Yes The fort 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, including during the Second English Civil War of 1648. The fort hosted an admiralty court to oversea the local oyster trade, but fell into decline and was extensively damaged by coastal erosion and the construction of a sea wall.[37]

West Tilbury Blockhouse Chadwell St Mary
51.45238°N 0.37357°E / 51.45238; 0.37357 (West Tilbury Blockhouse)
TQ651754		 1539 River Thames N/A The blockhouse was D-shaped, with a circular bastion facing the river. There were probably additional battery positions on both sides of the main defences, an additional outer ditch and ramparts were constructed in 1588.

SZ353897		 1545 Yarmouth Harbour Yes The castle comprised a square artillery fort, built around a central courtyard with an angular bastion protecting the landward side. The bastion was a departure from earlier approaches and Yarmouth was the first to adopt this Italian-styled design in England. It remained in military and government use until the 1950s.[58]

Notes
  1. In the 16th century, a variety of terms were used to describe these fortifications, including "blockhouses", "bulwarks", "castles" and "fortresses". Modern historians have also used different terms to describe and analyse the fortifications: B. Morley, for example, distinguishes between "Henrician castles" and "Henrician blockhouses"; Peter Harrington between the "castles/forts" and "blockhouses"; Andrew Saunders distinguishes between the "castles", "forts" and "blockhouses", but stresses the breadth of the Device programme across England and Wales.[3]
  2. Comparing 16th-century costs and prices with those of the modern period depends on the price comparison used. £376,000 in 1546 could be worth between £2,159 million and £67,260 million in 2015 terms, depending on the measure used.[8]
