Barclays Center is a multi-purpose indoor arena in the New York City borough of Brooklyn. The arena is part of a $4.9 billion future business and residential complex now known as Pacific Park. The site is at Atlantic Avenue, next to the renamed Atlantic Avenue–Barclays Center subway station on the 2, 3, 4, 5, B, D, N, Q, R and Wroutes, as well as directly above the LIRR's Atlantic Terminal.
The arena is home to the Brooklyn Nets of the National Basketball Association, and is also one of the home arenas for the New York Islanders of the National Hockey League (the other is Nassau Coliseum). The arena also hosts concerts, conventions and other sporting and entertainment events. It competes with other facilities in the New York metropolitan area, including Madison Square Garden in Manhattan and Prudential Center in Newark.
