Croton Aqueduct Gate House
Also known as: 135 Street Gate House
Why it's listed
Water for Manhattan once passed through this small but massive gate house at West 135th Street and Convent Avenue, beside Annunciation Park. Built between 1884 and 1890, it received water from the New Croton Aqueduct and regulated its distribution to the Central Park Reservoir and to northern Manhattan. The two-story building is faced with rough brownstone and granite and has a steep hipped roof, an octagonal tower and a terrace. Inside, granite-lined chambers, sluice gates and stop-cocks still control the flow, and most of the original equipment survives, though the valves were electrified in 1938. Its design is attributed to Frederick S. Cook, an assistant engineer in the aqueduct's drafting bureau, who used the Romanesque Revival style. It is one of the few major architectural features of the New Croton Aqueduct within the city limits, and it remains in service today.
Significance in brief: It is significant in engineering history as a surviving original component of the New Croton Aqueduct, a major nineteenth-century civil and hydraulic work. It is also a distinctive example of Romanesque Revival design adapted to a utilitarian civic structure. It retains integrity of design and materials, including most of its original mechanical systems.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
