Everyone knows about the 36 columns representing the states in the Union at the time of Lincoln’s death, but here’s the secret scoop: inside the memorial, there are hidden inscriptions on the ceiling beams containing the names of the states that were part of the Union and the years they joined. Another fun detail is the subtle “mistake” in the engraving of the Gettysburg Address: the word “FUTURE” was initially carved as “EUTURE” before being corrected. It’s still faintly visible if you know where to look.
