A Gothic Revival landmark open to all visitors, The Cathedral of St. John the Divine hosts daily services, concerts and choral performances, and public tours. Visitors can explore artwork by Keith Haring, 17th-century tapestries, stained-glass windows, gardens and wandering peacocks. The exhibit The Phoenix: Xu Bing at the Cathedral, on view through January 2015, is a feat of engineering and ingenuity. The monumental sculpture is composed of two birds, each weighing 12 tons and measuring nearly 100 feet long, built from construction debris in Beijing, China. They hang suspended in the cathedral's nave.
