The basilica of the archdiocese of Philadelphia is the spiritual center for the Philadelphia area's 1.4 million Roman Catholics. Topped by a huge copper dome, it was built between 1846 and 1864 in the Italian Renaissance style. Many of the interior decorations are by Constantino Brumidi, who painted the dome of the U.S. Capitol. Six Philadelphia bishops and archbishops are buried beneath the altar.
