The Sniffen Court Historic District is one of New York City's smallest historic districts, created on June 21, 1966, by the New York City Landmarks Preservation Commission. Sniffen Court, named after John Sniffen, a local builder, is a small close-ended mews that runs perpendicularly southwest off of East 36th Street between Third and Lexington Avenues in the Murray Hill neighborhood of Manhattan. The district encompasses the entire alley, which consists of 10 two-story brick stables built in 1863-1864 in the early Romanesque Revival style.
