Washington Heights, the narrow strip of high ground between the Harlem and Hudson Rivers, is named for the Revolutionary War Fort Washington.

Fortifications aside, the area was rural, rocky, and sparsely populated until latter half of the 19th century; the extension of rapid transit to Upper Manhattan century helped spur development. Today, Washington Heights is a diverse, densely populated enclave including the massive Columbia University medical campus, historic sites like the Morris-Jumel mansion, and panoramic views of the Bronx, Lower Manhattan, and the New Jersey Palisades.
