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.
Continuity mistake: After the Hessian, carrying Lady Van Tassel on his horse, jumps back into the tree, her hand is prominently displayed sticking out of the roots. Ichabod faints and it cuts to a wide shot of the entire tree. You can see where the Horseman jumped into the tree but Lady Van Tassel's hand is not there.
Continuity mistake: When Ichabod is being told the history of the Horseman, it shows the Horseman meeting the two Van Tassel children. After the Horseman motions for them to stay silent, young Lady Van Tassel raises the branch that she's holding and snaps it in half. Later, when Lady Van Tassel tells Katrina everything, another flashback seen occurs that shows a young Van Tassel simply breaking the branch without raising it first.
Continuity mistake: At the start of the movie where Ichabod is at the City of New York Municipal Watchhouse there is a medieval device to Ichabod's left, which is open and empty. In the following shot, there is a man standing inside with the doors closed around him.
