About Castle Shannon
Incorporated as a Borough in 1919 Castle Shannon derived its name from the most prominent farm in the area, then known as Castle Shanahan which evolved into Castle Shannon. This South Hills community is serviced by the Keystone Oaks School system which is a “jointure” with the Boroughs of Dormont and Green Tree. There are approximately 3800 households in this location. The subway “T” runs through most of the Borough and is a quick commute to downtown Pittsburgh. Lee Hartman (a famous animator) and Dennis Miller (comedian) both grew up in Castle Shannon.
