as farm land by the Dutch. The Dutch gave the land, then outside the city limits (Wall Street) to Angolan residents of the colony, intending for their plots and settlement to serve as a buffer zone to Native Americans outside the settlement. In 1643, a group of "half-freed" slaves and elders such as Domingo Anthony, Manuel Trumpeter and Catalina Anthony, received land grants to build and maintain farms in the areas containing and surrounding Washington Square Park. The families who received the land were no longer slaves, but had to give a portion of the profits they received from the land to the Dutch West India Company and pay annual land fees. Their children would be born as slaves, rather than free. The area became the core of an early African American community in New York, then called the Land of the Blacks and later "Little Africa". Among those who owned parcels in what is now Washington Square Park was Paulo D'Angola. It remained farmland until April 1797, when the Common Council of New York purchased the fields to the east of the Minetta (which were not yet within city limits) for a new potter's field, or public burial ground. It was used mainly for burying unknown or indigent people when they died. But when New York (which did not include this area yet) went through yellow fever epidemics in the early 19th century, most of those who died from yellow fever were also buried here, safely away from town, as a hygienic measure. A legend in many tourist guides says that the large elm at the northwest corner of the park, Hangman's Elm, was the old hanging tree. However, research indicates the tree was on the side of the former Minetta Creek that was the back garden of a private house. Records of only one public hanging at the potter's field exist. Two eyewitnesses to the recorded hanging differed on the location of the gallows. One said it had been put up at a spot where the fountain was prior to 2007 park redesign. Others placed the gallows closer to where the arch is now. However, the cemetery was closed in 1825. To this day, the remains of more than 20,000 bodies rest under Washington Square. Excavations have found tombstones under the park dating as far back as 1799. Creation of Washington Square In 1826 Alderman Abraham Valentine "introduced
