Mason Dixon Line – A State Historic Marker
Route 8, Marydel
A Crownstone of the Mason-Dixon Line is located in Marydel. The dividing line was surveyed in the 1760s by Charles Mason and Jeremiah Dixon to settle the contradictory land claims of the Penn and Calvert families. Caroline County’s eastern border was marked by 36 stones placed at one-mile intervals; while every 5 miles Crownstones were placed. 33 of the mile stones remain.
