Marble Hill is the northernmost section of the borough of Manhattan in New York, New York. It is separated from the rest of Manhattan by the Harlem River Ship Canal, which was dug in 1895 to connect two portions of the Harlem River bypassing a very circuitous portion and leaving Marble Hill as an island. In 1914, the old river was filled in, physically connecting Marble Hill to the borough of The Bronx. When a judge found it to be legally still a part of Manhattan in 1939, the Bronx Borough President declared it 'the Bronx Sudetenland', referencing Hitler's 1938 annexation of Czechoslovakia.
Marble Hill is named for the large deposits of marble underlying it. The formation, known as the Inwood marble , was formerly quarried for building stone.
Commuter Service to lower Manhattan, the Bronx, and the northern suburbs is available via the Marble Hill train station, served by Metro-North Railroad, as well as the 1 and 9 subway lines.
