Southwark is one of the oldest English settlements in the County of Philadelphia. It is actually the oldest district founded by settlers in Philadelphia, as a result of its inclusion in the former Swedish colony of New Sweden. Southwark was originally a tract of ground on the fast land of the Neck, lying between Passyunk and Wicaco. Due to the populations of the Swedish settlements of Wicaco and Moyamensing, Southwark grew earlier than other parts of the county apart from the city of Philadelphia.
