Dumbo (or DUMBO, an acronym for Down Under the Manhattan Bridge Overpass) is a neighborhood in the New York City borough of Brooklyn. It encompasses two sections: one situated between the Manhattan and Brooklyn Bridges, which connect Brooklyn to Manhattan across the East River, and another extending eastward from the Manhattan Bridge to the Vinegar Hill area. The neighborhood is bounded by Brooklyn Bridge Park to the north, the Brooklyn Bridge to the west, Brooklyn Heights to the south, and Vinegar Hill to the east. Dumbo is part of Brooklyn Community Board 2.
Dumbo has historically been known by several names, including Gairville, Rapailie, Olympia, and Walentasville. The area was originally a ferry landing, characterized by 19th- and early 20th-century industrial and warehouse buildings, Belgian block streets, and its location on the East River by the imposing anchorage of the Manhattan Bridge. A large number of the buildings in Dumbo were bought by developer David Walentas and his company Two Trees Management in the late 20th century, and remade into an upscale residential and commercial community—first becoming a haven for art galleries, and currently a center for technology startups.
