Hidden in a Crimean mountain under 180 metres of rock, Object 221 was meant to run the Soviet Black Sea Fleet through a nuclear war. It was never finished, then looted, and now it may be back in military hands.

Behind an ordinary-looking bungalow in the Essex countryside, a 100-yard tunnel leads down to a three-level bunker about 125 feet underground. Built in 1952 as an RAF command centre, it became a regional government headquarters for a nuclear war, and is now a museum.

Deep in a forest in north-west Lithuania, about 10,000 Soviet soldiers built an underground base for four nuclear missiles aimed at Western Europe. It was one of the first of its kind, was kept secret for years and was abandoned in 1978. Today one of its silos is a museum.

Twenty kilometres from the Wolf's Lair, the German army built a hidden town of more than 200 structures. The Germans never blew it up, so the concrete is still there.

A camouflaged bunker town in the Masurian woods, where Hitler spent more than 800 days, survived a bomb on 20 July 1944 and was blown up by his own army as the Red Army closed in.
