Plot hole: The tunnel at the base of the stairs under the church wasn't connected to the stairs and seems to only have been reachable with the elevator system.

Factual error: As Ben is clinging to the staircase while it is falling apart, there is a close-up of a nail being pulled out of the wood. This nail is round-headed, rather than square as it would have been over 200 years ago. It's also shiny instead of rusty, which indicates that it's galvanized. Galvanization as an industrial, metal-preservation process was not patented until 1837, and was not used in building materials until well into the late-1800s. Since the film states the staircase was made by "the Founding Fathers, " and there was no galvanization of iron nails in any industrialized nation in 1780s-1830's, this is a huge anachronism.

Trivia: Andrew Jackson's 1832 White House was actually filmed at the Daughters of the American Revolution Building in DC.
