Clarence Battery La Vallette. Constructed in 1780, Clarence Battery was built as one of the original outer defences of Fort George, Guernsey’s major military headquarters in the late 1780s. It was originally known as ‘Terres Point Battery’ but was renamed Clarence Battery in 1805 in honour of George III’s son.

The battery consists of numerous defences and thick walls. It's position gives it a superb view across St Peter Port and Castle Cornet, along with the Castle Breakwater.

It was the island’s principal fort during the French Revolution and home of the German Luftwaffe early warning system during World War Two. The battery had a guard room, gun pivots, ammunition lockers, shell stories and artillery stores. Some of it still remains, though some alterations were made by the Germans during the occupation.
