Hangman's Elm is believed to be Manhattan's oldest tree, dating back more than 300 years. Although it is famously known as the "Hanging Tree," historians have found no evidence that executions ever took place from its branches.
The legend likely grew from Washington Square's history as a potter's field and execution site. The only documented execution nearby was that of Rose Butler in 1820, who was hanged from a gallows some distance away. Even so, the tree's age, imposing presence, and proximity to thousands of burials have made it one of New York City's most enduring ghost-story landmarks.
