Ditmas Park is a landmarked Brooklyn enclave recognized for its freestanding Victorian, Colonial Revival, Tudor, and Craftsman homes set back from the street with porches and landscaped yards. The B and Q trains serve the neighborhood at Cortelyou Road, Beverley Road, Newkirk Plaza, and Avenue H stations, and Prospect Park's 526 acres of green space sit just to the northwest. The historic district encompasses roughly 2,000 residential buildings dating from 1902 to 1914, making it one of the city's best-preserved collections of early 20th-century residential architecture.
