Tribeca (tɹaɪˈbɛkə), originally written as TriBeCa, is a neighborhood in Lower Manhattan in New York City. Its name is a syllabic abbreviation of "Triangle Below Canal Street". The "triangle" (more accurately a quadrilateral) is bounded by Canal Street, West Street, Broadway, and Chambers Street. By the 2010s, a common marketing tactic was to extend Tribeca's southern boundary to either Vesey or Murray Streets to increase the appeal of property listings. The neighborhood began as farmland, then was a residential neighborhood in the early 19th century, before becoming a mercantile area centered on produce, dry goods, and textiles, and then transitioning to artists and then actors, models, entrepreneurs, and other celebrities. The neighborhood is home to the Tribeca Festival, which was created in response to the September 11 attacks, to reinvigorate the neighborhood and downtown after the destruction caused by the terrorist attacks. Tribeca is part of Manhattan Community District 1, and its primary ZIP Codes are 10007 and 10013. It is patrolled by the 1st Precinct of the New York City Police Department. Tribeca is one of a number of neighborhoods in New York City whose names are syllabic abbreviations or acronyms, including SoHo (South of Houston Street), NoHo (North of Houston Street), Nolita (North of Little Italy), NoMad (North of Madison Square), DUMBO (Down Under the Manhattan Bridge Overpass), and BoCoCa, the last of which is actually a collection of neighborhoods (Boerum Hill, Cobble Hill and Carroll Gardens). The name was coined in the early 1970s and originally applied to the area bounded by Broadway and Canal, Lispenard, and Church Streets, which appears to be a triangle on city planning maps. Residents of this area formed the TriBeCa Artists' Co-op in filing legal documents connected to a 1973 zoning dispute. According to a local historian, the name was misconstrued by a newspaper reporter as applying to a much larger area, which is how it came to be the name of the current neighborhood.
