Mount Rushmore
This one is more of a rumor. But many people believe that Abraham Lincoln’s head has a secret room. It’s called the Hall of Records and is right where the frontal lobe of Abraham Lincoln is. It contains some of America’s most important documents as if it’s straight out of the movie National Treasure. In the 1930s, designer Gutzon Borglum envisioned an 800-foot stairway leading to a grand hallway, with a large bronze eagle. And even though he died before that vision became a reality, there’s a record of America’s history inside the Hall of Records. No one is getting inside, as it’s sealed by a 1,200 pound of granite (Business Insider).
