Western Approaches Museum: Explore an underground bunker!

Derby House was a key operational hub during World War Two. Where you once had to sign the Official Secrets Act to enter, now you just need a smartphone ticket! This labyrinth-style bunker, originally the nerve-centre for the war-defining Battle of the Atlantic, is just as it was in 1945. Now home to the Western Approaches Museum, it's a time-capsule hidden beneath Liverpool City Centre.
