Coatesville, Pennsylvania: The Stargazers' Stone

Important and historic rock, encircled by an enclosure of lesser rocks. Mason and Dixon used it as a reference base while plotting their famous nation-bifurcating line. A second stone (with a plaque) was placed near the road in 2013.

899 Stargazers Rd, Coatesville, PA
On the right side of Stargazers Rd a couple hundred yards north of its junction with Hwy 162/Embreeville Rd. Set back a little way from the shoulder, where a well-manicured lawn meets the tree line. Look for a small enclosed area made of upright rocks.

Fake stargazing stone.

Stargazers' Stone

A stone with a plaque has been placed beside the stone house at the corner of Stargazers Road and Embreeville Road. It references a square stake in the street marking the original location of the astronomical observatory. Maybe they're trying to keep people from wandering around private property?

This bogus stone, placed in 2013, is nowhere near as interesting to look at as the real stone, placed in 1764, which is a couple hundred yards north on Stargazer Rd.

Found The Stargazers' Stone! I've been driving past it for a while.

Although it sounds like something from Native American times, the Stargazers' Stone was chosen by surveyors Mason and Dixon in the 1760s as a base point to plot the Mason-Dixon line, using star observations at night. The stone was arbitrary; they selected it because it was near a comfortable farmhouse and local taverns. And in fact the stone that you found isn't the Stargazers' Stone; it's the stone marker for the farmhouse (This is a common mistake). The Stargazers' Stone is about 100 yards further north on Stargazers' Road, behind some bushes and up a hill, in a cleared field surrounded by a low rock wall.

The stone is a walk away from the road. But it is in a private property field. If you drive slowly by you can take a picture of it.
