Surrounding communities


The first families settled Castle Shannon in 1786 in pursuit of farmland and timber. The most prominent farm was owned by David Strawbridge, which he named Castle Shanahan. Over time, the farm would lend its name to the area, as "Shanahan" would evolve into "Shannon."

In 1872, The Pittsburgh and Castle Shannon Railroad line was completed, providing a direct link from Pittsburgh to what was then known as the Village of Castle Shannon. Development was stimulated by two years of free transportation and lumber transport given to anybody building a home.[2] In 1877, a second railroad was built from Finleyville through Castle Shannon to the West End of Pittsburgh. In 1909, the right of way through the valley containing Castle Shannon was purchased by Pittsburgh Railroad. This helped lead to Castle Shannon becoming a center for coal mining, with 8 mines in operation in 1904. The Pittsburgh and West Virginia Railroad, still active today, came shortly after.

The First National Bank in Castle Shannon was the site of a much publicized bank robbery in 1917. $18,500 was taken in the robbery, of which $10,500 was immediately recovered from one man shot during the escape. The full sum was never recovered.

Castle Shannon was incorporated as a borough in 1919, formed from parts of Baldwin Township, Mt. Lebanon, and Bethel Township.

Castle Shannon’s school system, Keystone Oaks School District, is a jointure with the boroughs of Dormont and Green Tree, comprising Dormont Elementary School, Keystone Oaks Middle School and Keystone Oaks High School. Oddly enough, none of the three communities which make up the Keystone Oaks School District share a common border and the high school/middle school campus is located outside the district, being situated in the municipality of Mount Lebanon. Also, a small part of Castle Shannon is actually part of the Bethel Park School District.
