Washington Square Park, April 16, 1936.
What today might be a scene of benches covered in lodging students, a dog park, and buskers trying to make a dime, was once a potters field. In 1797, New York City bought a plot of land that had once been a farm to create a potter’s field—a burial ground for the indigent, poor, criminals, and victims of epidemic. Occupying what is now the eastern two-thirds of the park, the burial grounds remained open for more than 30 years. The area also hosted a hangman's gallows used by a nearby prison. By the 1810s the potter's field had largely been filled to its capacity (unsurprising with yellow fever epidemics in 1797, 1798, 1801, and 1803). Burial spaces for the Cedar Street and Pearl Street Presbyterian churches were also located nearby in the early 19th century.
In 1827 the area was declared a public square and over the next century became the park as we know it today.
