Est. 1827 · Potter's field 1797–1826 with estimated 20,000 burials · Site of Rose Butler execution 1820 · Hangman's Elm — one of Manhattan's oldest living trees (~350 years) · Brick burial vaults discovered on-site in 2015
The eastern portion of what is now Washington Square Park functioned as the city's potter's field from 1797 to 1826 — a public burial ground for the indigent, the unidentified, and epidemic victims, particularly during yellow fever outbreaks. An estimated 20,000 bodies remain in the ground beneath the park; the figure appears in NYC Parks documentation and has been corroborated by the discovery of intact brick burial vaults during construction work in 2015.
The city converted the land to a parade ground in 1826 and formally opened it as a public park in 1827. It became the center of the Greenwich Village neighborhood and has served as a public square, a protest site, a concert venue, and a chess park in the two centuries since.
The only documented execution in this area was that of Rose Butler, hanged on June 9, 1820, in the potter's field. Butler was nineteen years old, enslaved, and convicted of arson for attempting to burn down her enslaver's home while the household slept. The damage was minimal and no one was harmed; Butler was nonetheless sentenced to hang. The execution drew an estimated 10,000 spectators. Butler was hanged from a gallows in the eastern potter's field, approximately 500 feet from the Hangman's Elm — the tree stood on farmland to the west of the creek at the time.
The English elm in the northwest corner of the park has been assessed by NYC Parks as one of Manhattan's oldest living trees, with an estimated age placing its origin in the mid-17th century. The 'Hangman's Elm' designation first appeared in late-19th-century references, long after executions in the area had ceased. Wikipedia's article on the tree notes that no public records confirm any hanging from the elm itself.

Cold spots near the central fountainUnexplained voicesApparitions near the northwest corner
Washington Square Park's haunting reputation is almost entirely structural — 20,000 bodies beneath a busy public park is a circumstance that generates ghost stories reliably, and tour operators have worked the site for decades. Ghost City Tours and other operators document visitor accounts of cold spots concentrated near the central fountain, unexplained voices, and occasional apparition reports near the northwest corner where the elm stands.
The Hangman's Elm is the park's most-photographed paranormal landmark, though its name is a retroactive folk designation. Wikipedia's article on the tree notes that the earliest references to it as a 'hanging tree' date from the late 19th century, well after the actual execution site nearby had been built over. The elm stood on farmland west of Minetta Creek when Rose Butler was hanged in the potter's field to the east; the association between tree and execution is atmospheric rather than geographic.
The 2015 discovery of intact brick burial vaults during infrastructure work renewed press attention to the burial history. The vaults, found below street level at the park's southern edge, were documented in local news and added a tangible physical dimension to the archaeological layer that residents and visitors had long understood abstractly.
Rose Butler's execution — an enslaved woman hanged for arson she committed against her enslaver's household — has received more careful historical attention in recent years. The park's ghost lore has generally not centered her story, preferring the anonymous mass-burial narrative. Tour guides and historical accounts now more frequently note Butler by name.
