St. Patrick's Church, located on Fifth Avenue, is the largest Catholic church in the United States and is the patron saint of the Irish. When the Irish immigrants lived in New York in the 19th century, the church was established, and there was a march on March 17th, the St. Patrick's Day. The Gothic architecture has spectacular spires, flower windows, bronze statues, and three pipe organs inside the church. When the piano sounds, it seems to keep busy New York outside.
