Raise your hand if you knew that Delaware County is home to eastern Pennsylvania’s own version of Colonial Williamsburg! Nestled on 112 acres of Ridley Creek State Park in Edgmont, PA is the beautiful Colonial Pennsylvania Plantation. In the early 1970s, a local historical society established the beginnings of what would become Colonial Pennsylvania Plantation, formerly known as Bishop’s Mill Historical Institute, with the goal of showing visitors what life was like for an everyday person living and working at a farm or mill in the colonial period.
