Jefferson Market Library (former Jefferson Market Courthouse)

The Jefferson Market Courthouse, built in the 1870s and now the Jefferson Market Library branch of the New York Public Library, is frequently included in Greenwich Village ghost tours because of its history as a courthouse and proximity to a former women's prison. Staff and visitors have reported unexplained noises and occasional sightings within the building, and such stories are noted in local histories and tour literature. These accounts are traditionally presented as part of the building's cultural lore rather than as scientifically proven phenomena.
