Empire Fulton Ferry State Park

Empire–Fulton Ferry State Park is a state park in Brooklyn, New York, United States. The park is located next to the East River, extending north and south of the Brooklyn Bridge. The future Brooklyn Bridge Park, which will be operated by an agency of the City of New York, will extend the recreational waterfront area on the East River north and south of the Fulton Ferry State Park.

The southern part of the park is commonly referred to as Fulton Ferry Landing, a large pier, one of the most popular sites for photography in New York City. Behind it is the former Marine Company 7 Firehouse from 1924 with a tower for drying fire hoses.

The northern part of the park offers a lawn with picnic tables and a boardwalk with views of the East River, the Brooklyn Bridge, the Manhattan Bridge and Lower Manhattan. It also contains two historic buildings, the Empire Stores buildings and the roofless former Tobacco Warehouse. The Empire Stores is a former dry goods storage warehouse from 1880, mostly unused. It will be rehabilitated as part of the future Brooklyn Bridge Park, containing a mix of commercial, retail, and office uses. The Tobacco Warehouse serves as an outdoor entertainment area.
