Inside America’s Mount Rushmore National Monument there is a “secret” chamber known as the Hidden Hall of Records. Therein, under a 1,200 pound granite capstone, which is atop a titanium vault, which encloses a teakwood box, lie sixteen porcelain enamel panels with the texts of the Declaration of Independence, the Constitution, and the Bill of Rights etched upon them. It also houses a biography of Gutzon Borglum–the supervising sculptor of Mount Rushmore–and the story of the presidents. The builders’ intent was to preserve copies of these documents for the far future. Just outside the vault is an inscription reading:
“…let we place there, carved high, as close to heaven as we can, the words of our leaders, their faces, to show posterity what manner of men they were. Then breathe a prayer that these records will endure until the wind and the rain alone shall wear them away.”
–Gutzon Borglum, Sculptor
The Hidden Hall of Records is tucked amidst the cliffs on the backside of the mountain, and is not accessible to the public.
Relatedly, the carved heads are 80 times larger than an average human head. Originally Thomas Jefferson’s face was carved on Washington’s right, but the sculptors decided the rock there was too weak, so they blasted the face away and started again on Washington’s left. The original design of Mt. Rushmore included torsos, but funds ran short and builders stopped while they were a head.
