Factual error: At the very end of the movie, Ichabod addresses to Young Masbath saying the final line "You'll son find your bearings young Masbath. The Bronx is up, the Battery is down and home is this way." However the Bronx was instituted only in 1898, a century later.
Suggested correction: 1. The Bronx was established in 1639, along the Bronx river by Dutch settlers, they started using the name Bronx. It doesn't have to be part of New York City for Ichabod to mention the location of the Bronx. There was already 2 bridges to it from Manhattan island even. 2. He could be simply referring to the Bronx river.
