[4] Reamstown is located in northeastern Lancaster County at 40°12′43″N 76°7′3″W / 40.21194°N 76.11750°W / 40.21194; -76.11750 (40.212046, -76.117587),[5] in the southern part of East Cocalico Township.

PA 272 leads northeast 4 miles (6 km) to Adamstown and southwest the same distance to Ephrata.

"[6] During the American Revolution, Reamstown served as one of a number of field hospitals for the wounded following the Battle of Brandywine on September 11, 1777.

A dozen or more of these troops died here and are buried in unmarked graves in the Salem Evangelical Cemetery.

The cemetery is also home to a large boulder that once served as a mortar and pestle by the native people who lived on nearby Ephrata Mountain to the south.

It was transported to Reamstown by Pierce Lesher, and today a plaque on the stone details both the Native American and military history.
