The Basilica of Saint Patrick's Old Cathedral, or Old St. Patrick's, is located at 260–264 Mulberry Street between Prince and Houston Streets in the Nolita neighborhood of Manhattan, New York City, with the primary entrance currently located on Mott Street. Built between 1809 and 1815, and designed by Joseph-François Mangin in the Gothic Revival style, it was the seat of the Roman Catholic Archdiocese of New York until the current Saint Patrick's Cathedral opened in 1879.
