Fodor's Expert Review Old St. Mary's Church

The city's second-oldest Catholic church, circa 1763, became its first cathedral when the archdiocese was formed in 1810. Though the interior was renovated in the 1960s, the stained-glass windows and brass chandeliers that once hung in the Founders Room of Independence Hall are historic highlights. Commodore John Barry, a Revolutionary War naval hero, and other famous Philadelphians are buried in the small churchyard.
