Portsmouth has a new Scheduled Monument!
Lumps Fort has been added to the Schedule of nationally important archaeological sites. You can view the full entry on the National Heritage List for England here https://historicengland.org.uk/listing/the-list/list-entry/1490402?section=official-list-entry.
Lumps Fort was constructed between 1859 and 1861 as part of a plan to strengthen Portsmouth's defences against the threat of a French invasion. The fort helped to protect the eastern seaward approach to Portsmouth and its dockyard.
Portsmouth Corporation (now Portsmouth City Council) bought Lumps Fort in 1932 although it wasn't redeveloped for recreational use until after the Second World War.
During the early part of the war underground areas of the fort were used as air raid shelters. In 1942 it was the training base for the Royal Marine Boom Patrol Detachment, otherwise known as the 'Cockleshell Heroes'.
The rose garden was laid out between 1951 and 1953 and the model village opened in 1956/7. A Japanese Garden designed by Takashi Sawano was opened on the east side of the fort to celebrate the twinning of Portsmouth with the City of Maizuru in 2000.
The Victorian fort replaced an earlier coastal battery, Lumps Farm Battery, built in 1765. The battery was abandoned due to coastal erosion, the south part having been lost to the sea by 1838.
A much earlier fortification built in 1539, Chatterton's Bulwark, is thought to have probably been located within the vicinity of Lumps Farm, which was situated slightly north-east of the present fort. However, the exact location of the bulwark is unknown.
Lumps Fort is one of 19 Scheduled Monuments in Portsmouth. You can find out more about the city's Scheduled Monuments, Listed Buildings and Registered Parks on the National Heritage List for England https://historicengland.org.uk/listing/the-list/.
