below ground level, it is one of the deepest stations in the entire system by distance to ground level; it is even deeper than the 34th Street–Hudson Yards station, the deepest station in the system by elevation below sea level. Although this is an extremely deep station, the Bennett Avenue entrance is at a lower elevation than the platforms, so the ramp slopes down. Additionally, Dyckman Street, the next station north, is only one level below the surface, in contrast to the 190th Street station. Entrances and exits Contrary to the station's name, there are no exits to either 190th Street or Overlook Terrace. However, the station has entrances both to Hudson Heights, on top of the ridge, and to Bennett Avenue in the valley of Washington Heights, on the bottom. A tunnel leading eastward from the station provides access to Bennett Avenue, midblock between Broadway and 192nd Street, with an entrance built right into the rock face. The 207th Street-bound platform contains an exit-only (one turnstile and one gate) ramp that bypasses fare control and leads to the passageway to the Bennett Avenue entrance. Passengers used to be able to enter the station from the ramp, which is evidenced by tiled mosaics. The entrance at the top of the ridge is a head house located at the end of Fort Washington Avenue, at Margaret Corbin Circle. The station was built while the Cloisters in Fort Tryon Park were under construction, making it possible for the head house to have a stone facade to harmonize it with the entrance to the Cloisters several hundred feet north of the station's entrance. The head house is a single-story rectangular stone building with a black hip roof. The longer sides are on the western and eastern elevations, and each contain three bays. The northern elevation contains three small arches, of which the center arch contained a doorway into the head house. The southern elevation is abutted by stone stairs leading down to the station's elevators and a play area within Fort Tryon Park. A lamppost and a steel sign with the word "SUBWAY" is located on the sidewalk of Fort Washington Avenue at the top of these stairs. Elevators The station maintains three elevators from the mezzanine in one tower at its eastern end, and has done so since its opening. The elevators lead upward to the basement of the Fort Washington Avenue
