Watch House Battery is a former 19th-century gun battery, built as one of a number of batteries to defend the Eastern approaches to Plymouth Sound, for the defence of the Royal Naval Dockyard at Devonport.
The battery was originally built as a small pentagonal redoubt with emplacements for five guns. By 1893 it was armed with two 64 Pounder Rifled Muzzle Loading Guns. In 1901 the battery was reconstructed for two 6-inch Mark VII breech loading guns with the work being completed in 1903.[1] During the First World War the battery was manned by the Devonshire Royal Garrison Artillery.[2]
After the Second World War the battery remained armed until the dissolution of coast artillery in the United Kingdom in 1956 when it was disarmed.[3] It was released by the military and subsequently used as a children's activity centre for some years.[4] It was Grade II listed in 1969.
