The Meatpacking District is a neighborhood in lower Manhattan, bounded by West 14th Street, Gansevoort Street, Hudson Street and the Hudson River. Over the last two decades, upscale loft residential buildings converted from commercial warehouses, as well as nightclubs, restaurants and boutiques have replaced the meatpacking plants that gave the neighborhood its moniker. Before the Civil War, the neighborhood was home to a variety of industries, including ironworks, terra cotta manufacturing, carpentry and woodworking, lumber yards, granite works and a plaster mill. In the 2000s, the development and opening of the High Line, a public park created on an abandoned elevated train track, helped precipitate even more development of luxury hotels and condominiums in buildings designed by celebrity architects. These include the 14-story Hotel Gansevoort, opened in 2004, and the Standard High Line, which straddles the elevated park and was completed in 2009. The Whitney Museum of American Art moved to a new building designed by Renzo Piano at 99 Gansevoort Street on the corner of Washington Street in May 2015.
