Marble Hill, Manhattan

Marble Hill is the northernmost neighborhood in the New York Cityborough of Manhattan. The neighborhood is bordered by Johnson Avenue on the west, 230th Street on the north, Broadway on the east, and Spuyten Duyvil Creek to the south. Although Marble Hill is legally considered part of Manhattan, it is physically connected to the borough of the Bronx and is not part of the island of Manhattan.
The area later known as Marble Hill became a Dutch colonial settlement in 1646. It served as a crossing point to the mainland when the colonial British had the King's Bridge constructed in 1693 to span the Spuyten Duyvil Creek. It gained its name in 1891 from the Inwood marble deposits discovered underneath the neighborhood. At one time, Marble Hill was part of the island of Manhattan. The neighborhood became a separate island in 1817 when two small streams were dug up to form a narrow canal that separated Marble Hill from the rest of Manhattan. In 1895, the canal was expanded and became the Harlem River Ship Canal. Marble Hill remained an island until it was physically connected to the Bronx by land reclamation in 1913.
Marble Hill is accessible from the rest of Manhattan by the Broadway Bridge. The neighborhood has Bronx area codes and a Bronx ZIP code; furthermore, it is part of Bronx Community District 8 and is served by the New York City Police Department's 50th Precinct, headquartered in the Bronx.
