The Mount Morris Bank Building, also referred to as the Corn Exchange Bank and Corn Exchange Building, is an historic building in the East Harlem neighborhood of Manhattan, New York City, located at 81-85 East 125th Street on the northwest corner of Park Avenue. Although an architectural standout when new in 1883, by the late 1970s it was vacant, and remained so for three decades, vandalized and deteriorating. In 2009 the city demolished, for safety, most of what remained after a 1997 fire, but in 2012 a developer undertook to rebuild it for commercial occupancy, and the building reöpened in May 2015.The building was added to the National Register of Historic Places in 1989, and was designated a New York City Landmark in 1993.The banking yearsThe Mount Morris Bank was organized in December 1880 when Harlem was being transformed from a suburb into an urban residential neighborhood, connected to downtown commercial and residential districts by the new Manhattan Railway Company lines. The bank initially rented space at 133 East 125th Street, just west of Lexington Avenue.Construction began on its new building - which was selected by competition and located at 81, 83, and 85 East 125th Street - on April 3, 1883 and was completed on February 1, 1884, although the bank, occupying the main floor, moved in by late 1883. Like its plainer neighbors, the building was designed for a mix of commercial and residential use. The basement, partially above ground, was initially occupied by the Mount Morris Safe Deposit Company at #83, which built and owned the building. There were six apartments on four floors above the commercial space, plus an attic. The apartments - called "The Morris" - were completely separated from the banking portion of the building. They had their own entrance at #81 and were served by an elevator, but they barely lasted two decades: by the early twentieth century the apartments were converted into offices.
