Schaefferstown is one of the oldest towns in Lebanon County, being at least a century older than the county itself. It is the main town in Heidelberg Township. Although the exact date of the first settlers is unknown, it is certain that they settled here before 1725. Those first settlers were German Jews. Many of them were skilled craftmen and traders. They disappeared, however, when non-Jewish German settlers started moving into the area. The old burial ground was situated about a fourth mile south of Tower Hill and almost a hundred yards east of South Market Street in Schaefferstown. The Jewish settlement was known as the Lebanon Trading Post.
Schaefferstown held a Bicentenntial in 1963.
Brendle Farms, Philip Erpff House, and Rex House are listed on the National Register of Historic Places. Bomberger's Distillery, also listed, is located near Schaefferstown. The Schaeffer House was added to the National Register of Historic Places and designated a National Historic Landmark in 2011.

The water company in Schaefferstown has the oldest gravitational conveyance system by underground pipes in the United States. The water system was constructed sometime between 1744 and 1750 by the founder of the town, Alexander Schaeffer. The water system, which is located in the area now known as Fountain Park, is still used by the townspeople for potable household water. When the original system was laid out, it ran to two wooden troughs on the Square, which is now the intersection of Main St. and Market St. One trough was since replaced by Matilda Zimmerman in memory of Mary Rex Zimmerman, her mother and great granddaughter of Alexander Schaeffer. This trough is now located on the south face of the historic bank located within the Square.
