Sandsfoot Castle

Sandsfoot Castle stands on the Dorset coast near Weymouth, a ruined artillery fort built by Henry VIII in the 16th century. It was designed to defend Weymouth Bay with an octagonal gun platform and a blockhouse, completed by 1542 at a cost of £3,887. The castle’s position on unstable clay cliffs made erosion a constant threat, and repairs were needed as early as 1583. By the 18th century it had fallen into ruin, its stone reused in local buildings including Weymouth’s town bridge. Earthwork defences added in 1623 once protected the landward side, but the seaward walls steadily collapsed. The fort saw action during the English Civil War, changing hands between Parliamentarians and Royalists. In 1643 it was briefly held by the Earl of Carnarvon’s Royalist forces before being retaken by the Earl of Essex’s Parliamentarians. After the Restoration, the castle was declared redundant in 1665 and left to decay. Historic England recognises Sandsfoot as one of the most substantial surviving 16th-century blockhouses in England. Its ruins were closed to visitors in 2021 due to safety concerns after further erosion. Visitors today find a grassy site beside the crumbling stone walls, with views across Weymouth Bay towards Portland. The remaining structure includes parts of the gun platform and residential blockhouse, though much has been lost to the sea. Nearby civic gardens planted in 1951 offer a place to walk, while the castle’s history is marked by carved arms moved to All Saints Church in Wyke Regis. The unstable cliffs and ruined walls tell the story of a fort that once defended England against invasion.
