Welcome to the official website of Colwyn Borough, located in Delaware County, Pennsylvania. Incorporated in 1682, Colwyn consists of 0.3-square miles of primarily residential land bordering the City of Philadelphia.
The borough is served by its own police and fire departments and is a part of the William Penn School District. Positioned just over two miles from Philadelphia International Airport and Interstate 95, Colwyn is easily accessible from the entire metropolitan area and beyond. Additionally, the borough is well-served by public transit, with SEPTA train, trolley and bus service linking Colwyn to Center City Philadelphia and greater Delaware County.
