New Attractions in New York City

The biggest news in Brooklyn is the arrival of this new 18,000-seat arena located above a rail yard where nine subway lines and several major avenues converge. It is a spectacular structure of Cor-Ten steel designed by SHoP Architects (with AECOM), featuring an ambitious public-art program to boot. Jay-Z will christen the new arrival with a concert on September 28; two weeks later, Barbra Streisand will give her first performance in Brooklyn in 50 years. Then the Nets, partly owned by Jay-Z, will become the first professional sports team to play in Brooklyn since the Dodgers left. 620 Atlantic Ave.; 212-359-6387; barclayscenter.com.
