The smallest New York parcel of land is a triangle about 2 feet by 2 feet by 2 feet.
The lot, referred to as The Hess triangle, is a triangular, 500-square-inch (3,200 cm2) plot of private land in the middle of a public sidewalk at the corner of Seventh Avenue and Christopher Street in the West Village neighborhood of Manhattan, New York City. The plot is an isosceles triangle covered by a mosaic plaque that reads “Property of the Hess Estate which has never been dedicated for public purposes.”
