Hess Triangle

The Hess triangle is a triangular tile mosaic set in a sidewalk in New York City's West Village neighborhood at the corner of Seventh Avenue and Christopher Street. The plaque reads "Property of the Hess Estate which has never been dedicated for public purposes." The plaque is an isosceles triangle, with a 25+1⁄2-inch base and 27+1⁄2-inch legs.The plaque is the result of a dispute between the city government and the estate of David Hess, a landlord from Philadelphia who owned the Voorhis, a five-story apartment building. In the early 1910s, the city claimed eminent domain to expropriate and demolish 253 buildings in the area in order to widen Seventh Avenue and expand the IRT subway.
