Peek inside the secret network of war bunkers: visit the Map Room, Transatlantic Telephone Room, and Cabinet Rooms.

Christopher Wren’s architectural masterpiece is not only one of London’s most famous landmarks, but it also served as an important symbol of hope and resilience for Londoners during WWII.

However, despite a Nazi bomb piercing the cathedral’s dome and damaging the high altar, the sacred monument stood strong.

Another one of the United Kingdom’s most important military museums is found in the affluent West London borough of Chelsea.

In addition to learning about the role of British battalions during WWII, there’s a fascinating exhibition devoted to the work of British soldiers in post-WWII Germany.

Look inside the recreated codebreakers’ huts, see the world’s largest collection of Enigma machines, and visit the National Museum of Computing.
