What lies beneath...

Talk about hiding in plain sight…each of these secret spots can be found in a famous landmark you may have visited.
The bomb shelter in the White House

You’d think the White House, in Washington DC, USA, would have lots of secret spaces, but there’s only one you’re allowed to know about without security clearance, and even that’s not exactly public knowledge. We’re talking about the bomb shelter President Franklin Delano Roosevelt had constructed in the East Wing in December 1941. While he was having it built, “mum” was the word; he acknowledged only that the East Wing construction was under construction. Washington DC is also the location of some of the 11 biggest lies ever told in history.
Secret passage in Buckingham Palace

Maybe the reason we associate secret passages with the dwellings of heads of state is that secret passages are pretty much standard fare in royal palaces. For example, Buckingham Palace has a secret door in the White Drawing Room, which connects to The Queen’s private residence. Although the White Drawing Room is open to visitors, the door is not.
