The Western one-third of Cumberland County contains a multitude of historic structures; approximately two thousand of these were surveyed from September 1984 to September 1985 as part of a project sponsored by the Cumberland County Historical Society and the Pennsylvania Bureau for Historic Preservation.
The early history of Pennsylvania is sprinkled with the exploits of daring, energetic, and forceful individuals. One of the most fearless and dedicated, yet least remembered of these personalities, was Christian Frederick Post. A humble man of God, he spent over forty years among the Indians and Whites of colonial America, spreading the Gospel and working for peace. He passed some of this time traveling through or living within the present borders of Cumberland County.
Penn Township was erected 23 October 1860 when the western half of Dickinson Township was made into a separate political and territorial body. Its creation was the result of a continuing effort lasting for at least twenty years. This subdivision was but one in a series of similar moves begun at the settlement of the Province and continued in Cumberland County until 1929.
Dr. Silas C. Swallow had already established a widely circulated reputation for being a determined fighter against the evils of strong drink and drugs before he became a resident of Cumberland County. The good Doctor of Divinity had other lesser-known qualities of character which were revealed during the ten years he lived in Camp Hill.
During ten generations the area now known as Camp Hill has borne five other names: Hendricks, Fort Pleasant, Oysters Point, Bowmanstown, and White Hall. Since 10 November 1885 an incorporated borough, it is part of the West Shore community that in 1731 was offered to Indian tribes as a reservation and in 1750 became the Penn family's Manor of Lowther.
