The cornerstone has secrets (well, not actually secrets because anyone who does any research knows about them), but a portrait of George, copies of the Constitution and the Declaration of Independence are all hidden inside.
Abraham Lincoln, James Buchanan and Andrew Jackson all attended the cornerstone ceremony back in 1848.
Ok, this is weird. People had to climb 898 steps to the top (when it first opened), so an elevator was added. But the elevator was “dangerous for women and children so they can’t ride.” Why would an elevator be dangerous to women and children, but not men? At first, the elevator took 10 minutes, now it takes 70 seconds. (We did not go up the elevator, nor the steps — tickets were gone.)
