The Croton Aqueduct Gate House is located in Manhattanville, Manhattan, New York City, New York. The building was built in 1884 and was added to the National Register of Historic Places on September 22, 1983. After being decommissioned in 1984, the below-grade valve chambers were filled and the building sat empty for nearly two decades. Between 2004 and 2006, architects oversaw an adaptive reuse project converting the gate house into theater space for Harlem Stage/Aaron Davis Hall.
