Newhaven Fort

Newhaven Fort stands on cliffs above the harbour at Newhaven on England’s south coast. Built in the 19th century as a Palmerston fort, it was the largest defence work ever constructed in Sussex. The site already held a 16th-century battery when Lieutenant John Charles Ardagh designed the new fort to follow the natural contours. A wide moat lined with concrete protected three sides, using the material for the first time on this scale in Britain. Ardagh also patented the main entrance bridge, which kept the fort’s outline low and unobtrusive. The fort’s guns defended the harbour through changing times. In the 1870s it mounted two 9-inch rifled muzzle-loaders on disappearing carriages, the only such arrangement in the country. By 1906 these had been replaced by modern 6-inch and 12-pounder guns, and in 1941 the fort received new BL 6-inch Mk 24 coastal guns. During the Second World War the 521st Coast Regiment manned the position. After the army left in 1962, restoration began in 1982 and the fort opened as a museum. Visitors walk through restored barracks built into the ramparts and see the re-installed 6-inch Mk VII guns that served from 1906 to 1941. The network of tunnels that once linked gun positions now features in films and festivals. The fort’s architecture and spaces host the Fort Process sonic arts festival, using its unique setting for temporary installations. From the cliffs there are views across the harbour and the English Channel, linking the fort’s military past with the working port below.
