Orphan Asylum, operated by the Sisters of Charity. In 1851, the asylum became for girls only, and in 1886 became St. Patrick's Convent and Girls School, before turning co-educational again. The Federal-style building is a New York City landmark, designated in 1966. The school finally closed in 2010 as enrollment dwindled, and the building was converted into residential and office space. In 1859, a "Gingerbread Gothic" Chancery Office Building was built at 266 Mulberry Street, just north of the sanctuary, designed by James Renwick Jr. and William Rodrigue, who would go on to design the new cathedral. The building would later become St. Michael's Chapel and, from 1936 until 2019, St. Michael's Russian Catholic Church of the Byzantine Rite. St. Michael's is the last Russian Catholic church in New York City, and was one of only four remaining such sanctuaries in the United States. Those services are now held at the Church of St. Catherine of Siena, 411 East 68th Street on the Upper East Side of Manhattan. Underneath the basilica are catacombs which currently consist of 35 family crypts and 5 clerical vaults, and which have reopened to new interments. The basilica has also opened the catacombs to walking tours led by "Tommy's New York". Among the notable interments are the first resident Bishop of New York John Connolly, General Thomas Eckert, several members of the Delmonico restaurant family, Countess Annie Leary, the prominent wine merchant Dominick Lynch, and Congressman John Kelly. In addition, two New Yorkers who are currently on the road to sainthood, Pierre Toussaint and Father Isaac Hecker, were originally interred there before being moved; Toussaint to the new St. Patrick's Cathedral, and Hecker to St. Paul the Apostle Church. The founding mother superior of New York's first Sisters of Mercy convent, Mary Agnes O'Connor, is also buried there. Old St. Patrick's Cathedral gallery holds a large pipe organ that was built in 1868 by Henry Erben, originally operated without any use of electricity. After the new cathedral opened uptown in 1879, the Erben organ was left downtown with minimal alterations. In 2004, the Organ Historical Society designated it as an instrument of "exceptional historical merit, worthy of preservation", the organ equivalent of national landmark status. The instrument remains in use for Sunday services while awaiting further restoration. In popular culture The baptism scene in The Godfather was filmed in the old Cathedral, as was the
