Archcliffe Fort

Archcliffe Fort is a former military installation in Dover, England. It is situated at the base of the Dover Western Heights and overlooks the approaches to the port of Dover. A watchtower was erected on the site in 1370 but this was replaced with a more substantial fort by Henry VIII by 1539. The fort fell into disrepair but was renovated in 1588 due to concerns over the Spanish Armada. The Stuart kings James VI and I and Charles I made improvements to the fort and it was heavily garrisoned by Charles II in the aftermath of the 1660 Stuart Restoration. Invasion scares during the long eighteenth century saw further improvements to the defences. The fort was manned during the First World War but in the 1920s much of it was demolished to allow for improvements to be made to the South Eastern Main Line railway. The fort was deemed obsolete by the time of the Second World War and was decommissioned in 1956, after which further demolition took place to widen the A20 road. The surviving structure includes two ramparts and two complete corner bastions, together with some modern buildings in the interior. The fort is used by the Emmaus Community to house formerly homeless people and operates a furniture workshop and retail centre.

The site sits at the base of the Dover Western Heights and overlooks Shakespeare Beach and the approaches to the port of Dover. Worked flint dating to the Neolithic and Bronze Age periods has been found here as well as pottery dating from the 12th to 14th centuries. In 1370 a watchtower was erected on the site. No traces of the structure remain but plans from the period show a pentagon-shaped building in the approximate location of the current western bastion. The plans show that the watchtower was connected by a ditch to a gatehouse located in the vicinity of the current eastern bastion.

In 1534 Henry VIII's parliament passed the Act of Supremacy, bringing the Church of England under his control and breaking with the Catholic Church. This led to fears of a Catholic-led invasion of England. Henry began constructing Device Forts to protect his lands including, by 1539, new fortifications at Dover. The existing watchtower at Archcliffe was demolished and a new fort erected. Archcliffe Fort was a rectangular, timber-revetted earth structure enclosing a gunner's house and a number of other buildings. Archcliffe Fort covered the western side of the harbour with Moat's Bulwark near Dover Castle erected to cover the east and Wyke Bulwark cut into the cliff itself to protect the pier (this fortification fell into disuse by 1568). The new fortifications were intended to destroy any invading force with cannonfire while it was still at sea or in the process of landing. Archcliffe Fort was equipped with a demi-culverin, two brass sakers, an iron fowler, three serpentines and a dozen bases. It had a permanent staff of a captain and two soldiers, intended to be augmented with additional troops in times of war. After the threat of invasion receded the fort and its guns fell into disrepair until 1588 when Elizabeth I carried out restoration works in response to the threat of the Spanish Armada.

Dover was an important embarkation point for English troops involved in the Eighty Years' War in continental Europe and in the early 17th century James VI and I (r. 1603–1625) ordered repairs made to Archcliffe Fort to improve the port's defences. James' successor Charles I (r. 1624–1649) ordered the cliff below the fort to be steepened to make it more difficult for an attacker to scale. In 1639 the fort was completely rebuilt at a cost of £4,300 (equivalent to £853,102 in 2025). Further works were carried out in 1641 which saw the fort encircled with a 7-foot (2.1 m) deep and 18-foot (5.5 m) wide ditch and a 20-foot (6.1 m) high per
