St. Patrick's Cathedral is the seat of the Roman Catholic archdiocese of New York. The nave of this enormous, ornate, Gothic-style building opened in 1879, and construction was completed in 1931. It now seats 2,200 people. The cathedral was designed by architect James Renwick Jr., and the St. Michael and St. Louis Altars were made by Tiffany & Co. The soaring columns, brilliant stained-glass windows—including the dramatic rose window over the west entrance—and sculpture are breathtaking. The cathedral hosts a variety of organ and choral concerts. Visit the cathedral Web site for an event schedule. Daily 6:30 am-8:45 pm.
