Location: Horse Guards Parade, Westminster, SE11 4UH
Description: The Admiralty Citadel is London's most visible military citadel, situated under heavy ivy, behind the Admiralty building on Horse Guards Parade.
It was constructed in 19401941 as a bomb-proof operations centre for the Admiralty, with foundations 30 feet deep and a concrete roof 20 feet thick.
It's linked by tunnels to government buildings in Whitehall. Sir Winston Churchill described it in his memoirs as a vast monstrosity which weighs upon the Horse Guards Parade.
The Admiralty Citadel is still used today by the Ministry of Defence.
