St. Patrick's Cathedral is a neo-Gothic church which functions as the Catholic Cathedral in the US. It's the see of the Archbishop of the Roman Catholic Church and is found at the famous Rockefeller Center, on 5th Avenue. James Renwick Jr. designed it, and the foundation stone was laid in August 1858. The interior is gorgeous, especially the old Lady Chapel, which was renovated in 1927. The great organ was installed in 1931. In 1976 it was declared a National Historic Landmark.
