ABOUT THE COMMUNITY THIS POST OFFICE SERVES
Castle Shannon
The first families settled Castle Shannon in 1786 in pursuit of farmland and timber. The most prominent farm was owned by David Strawbridge, who named it 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 the then-village of Castle Shannon. Development was stimulated by two years of free transportation and lumber transport given to anybody building a home.[4] In 1877, a second railroad was built from Finleyville through Castle Shannon to the West End neighborhood of Pittsburgh. In 1909, the right of way through the valley containing Castle Shannon was purchased by the Pittsburgh Railroad. This helped lead to Castle Shannon becoming a center for coal mining, with eight mines in operation in 1904. The Pittsburgh and West Virginia Railroad, still active today, came shortly afterward.

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.

Mount Lebanon
The first settlers arrived in 1773-1774, having purchased the land from the descendants of William Penn; other pioneers soon bought land from the state government.

In 1912, Mount Lebanon Township was incorporated as a "First Class Township" under Pennsylvania state law. It had formerly been a part of Scott Township, which in turn traces its origins to the long-defunct St. Clair Township. Mount Lebanon was not named for two Cedar of Lebanon trees that were planted in 1850 on Washington Road near the top of Bower Hill Road, but was named after the area from which they came, Mount Lebanon, due to the similarities between the two landscapes. Prior to the incorporation of the township, the "Mount Lebanon" name was used for the area of Upper St. Clair Township near the cedar trees. In the 1880s, a post office located near the transplanted cedar trees was named "Mount Lebanon". Incorporators of neighboring Dormont Borough initially tried to use the "Mount Lebanon" name in 1909, but were opposed by residents of the future Mount Lebanon Township.

In 1928, Mount Lebanon became the first First Class township in Pennsylvania to adopt the council-manager form of government and has had an appointed manager serving as the chief administrative officer since that time.

Mount Lebanon was a farming community until the arrival of streetcar lines, the first line to Pittsburgh opening on July 1, 1901 followed by a second in 1924. After the arrival of the streetcar lines, which enabled daily commuting to and from Downtown Pittsburgh, Mount Lebanon became a streetcar suburb, with the first real estate subdivision being laid out in November 1901. Further, the opening of the Liberty Tubes in 1924 allowed easy automobile access to Pittsburgh. Between the 1920 and 1930 censuses, the township's population skyrocketed from 2,258 to 13,403. Today, Pittsburgh's mass transit agency, the Port Authority of Allegheny County, or "PATransit," operates a light rail system whose Red Line, which runs underneath Uptown Mt. Lebanon through the Mt. Lebanon Tunnel, merges with the 47L line in Pittsburgh's Mt. Washington section. Mt. Lebanon's only platform station, Mt. Lebanon Station, is in Uptown Mt. Lebanon; the adjacent Dormont Junction and Castle Shannon stations are in neighboring municipalities. And as of the census of 2000, there were 33,017 people living in Mt. Lebanon.

On May 21, 1974, the electorate approved a Home Rule Charter, which took effect on January 1, 1975; as such, the community is no longer governed under the provisions of the Pennsylvania Township Code. Mount Lebanon became one of the first municipalities in Pennsylvania to adopt a home rule charter. In the charter, the official name of the municipality became Mt. Lebanon, Pennsylvania; the word "Mount" is abbreviated in all government documents, although the U.S. Postal Service continues to use "Mount."

The subdivision of Carelton Hills won a national liveability award in 1974
