Built in 1700 by Swedish Lutheran settlers on the Delaware River waterfront, Gloria Dei is Philadelphia's oldest surviving church and one of the oldest in the United States, with an active congregation that has worshipped continuously for over 320 years. The church preserves Swedish colonial artifacts including a cradle and chest brought from Sweden in the 17th century, as well as the grave of Nils Collin, the church's 18th-century pastor.
