Prospect Heights is a neighborhood in the northwest of the New York City borough of Brooklyn. The traditional boundaries are Flatbush Avenue to the west, Atlantic Avenue to the north, Eastern Parkway – beginning at Grand Army Plaza – to the south, and Washington Avenue to the east. In the northern section of Prospect Heights are the Vanderbilt Rail Yards, built over as part of the Pacific Park (formerly Atlantic Yards) project. The Barclays Center, home to the NBA's Brooklyn Nets basketball team and the NHL's New York Islanders ice hockey team, is located in the northwestern corner of the neighborhood in Pacific Park at Flatbush and Atlantic Avenues.
Compared to other Brooklyn neighborhoods, Prospect Heights is relatively small and is notable for its cultural diversity as well as its tree-lined streets. Prospect Heights has seen rapid demographic changes over the last decade, and its shifts are exemplified by a mixture of older buildings under reconstruction, rows of classic 1890s brownstones, and newly built luxury condominiums. The neighborhood is served by the New York Police Department's 77th Precinct.
