@thehistorymagpie: A major new exhibition detailing some of the world’s most mysterious, secret, and censored maps is now open to visit at @britishlibrary 🗺 Ad Running until 18 January 2026, Secret Maps uncovers how, across history, maps have been used to conceal as much as they reveal 👀 Inside, you’ll experience maps from as early as the 14th century, right through to the present day, and I can’t recommend it enough. What an amazing insight into a world you and I were never meant to see... @British Library #thingstodoinlondon #london #britishlibrary #historytok
