Mount Rushmore

This iconic U.S. landmark has a hidden feature. Behind the head of Abraham Lincoln, there is a secret door. The sculptor who designed Mount Rushmore, Gutzon Borglum, wanted the monument to include a written description of the nine most important events in U.S. history. However, his plan was too intricate and he was only approved to work on a Hall of Records (the hidden room). He died before it was completed, but copies of the Declaration of Independence, Constitution, and the Bill of Rights are on display in the room today. Very few people have actually been able to visit this room, though, because it’s difficult to reach by foot. If you decide to go, here’s your guide to a Mount Rushmore trip.

Everyone who has visited the Lincoln Memorial has probably noticed the typo in it, but they likely didn’t spot the hidden door. It leads to the building’s foundation, which basically is another monument on its own. A cave-like structure with concrete pillars and even stalactites can be found underneath the monument after traveling through the door and down several staircases.

Statue of Liberty

There is actually a room in the torch of the Statue of Liberty that showcases breathtaking views of the city. People used to be able to visit that room until 1916 when German agents blew up a nearby pier. The explosion sent debris into the raised arm of Lady Liberty, making the staircase up to the hidden room unsafe. Check out these famous moments in history that never actually happened.

Trafalgar Square

Only those with a very observant eye will notice the tiny Lilliputian Police Station located in Trafalgar Square in London. During the 1930s, Trafalgar Square was the go-to place for protests, so police hollowed out a lamp post in the square to be an inconspicuous spot for them to watch over the crowd.
