Fort Christina (later renamed Fort Altena; Swedish: Fort Kristina) was the first Swedish settlement in North America and the principal settlement of the New Sweden colony. Built in 1638 and named after Queen Christina of Sweden, it was located approximately 1 mi (1.6 km) east of the present downtown Wilmington, Delaware, at the confluence of the Brandywine River and the Christina River, approximately 2 mi (3 km) upstream from the mouth of the Christina on the Delaware River.
