Landenberg is an unincorporated community in southern Chester County, Pennsylvania, United States.
Hendrickson House, built in Chester in 1690 by Swedish farmers, was moved to Wilmington, Delaware, in 1958. By 1682, Upland was the most populous town of the new Province of Pennsylvania. On October 27, the ship Welcome arrived at the town, bearing William Penn on his first visit to the province. Penn renamed the settlement for the English city of Chester. Chester served as the county seat for Chester County, which then stretched from the Delaware River to the Susquehanna River.
