Borough of Castle Shannon

Nestled in a scenic valley just six miles from Downtown, Castle Shannon Borough was incorporated in 1919 from parts of Baldwin Township, Mt. Lebanon and Bethel Township.   Castle Shannon’s well-maintained neighborhoods, schools and businesses offer residents an affordable, convenient, and desirable place to live.

Castle Shannon offers easy access to major highways and swift transportation to Downtown by the light rail transit system.  Housing vacancy rates remain low and elementary school enrollment in Castle Shannon have been on the rise for several years.

The Castle Shannon Revitalization Corporation was founded in 2009 to improve the Castle Shannon Business District through growth and development. It is operated by citizens, neighbors, business owners, parents, and other active participants in Castle Shannon.  Its projects include a streetscape plan and watershed development.
