Western Approaches Museum

Derby House was a key operational hub during World War Two. Where once you had to sign the Official Secrets Act to enter, now you just need a smartphone ticket! * This labyrinthine bunker, once 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. * See original documents, tools, and maps used to analyse the enemy, plus one of two surviving phones that had a direct line to Churchill's War Rooms!
