Where exactly Is Marble Hill?

Geographically, this little neighborhood—which supplied the city with prime Inwood marble used to construct many landmark buildings—is connected to mainland United States.

You’d think it was in the Bronx. But it’s officially part of Manhattan.

This map weirdness happened when the city enlarged the Harlem River ship channel in 1895. That turned Marble Hill—then at the northernmost tip of Manhattan, separated from the Bronx by Spuyten Duyvil Creek—into an island, with the Harlem River on its north and the creek to the south.

In 1914, the creek was filled in, cleaving Marble Hill to the Bronx, though it was declared Manhattan territory in 1897.

Over the years, which borough it belonged to was brought into question. In 1939, the Bronx borough president planted a Bronx flag at Marble Hill and demanded that all residents submit to Bronx rule—a really bad joke met with resounding boos by dozens of Marble Hill residents.

In 1984, it was settled: the neighborhood is in Manhattan—albeit with a 718 area code, a Bronx zip code, and kind of a split identity.

    […] Marble Hill- once part of Manhattan Island…than an island of its own…then attached to the mainland and The Bronx…legally still part of Manhattan (New York County). […]

    Indeed, the Marble Hill is an anomaly in Manhattan. What is most interesting is that Marble Hill receives Bronx emergency services and is part of the Bronx area code and zip code, however, the neighborhood is still legally in Manhattan. We’re curious as to if this will ever change or forever be a reminder of the city’s past.


    I grew up in the Marble Hill projects and never considered myself a Manhattanite. My school district and zip code were Bronx. The Broadway Bridge was considered the dividing line between Manhattan and the Bronx.
