Cresap's Fort

Lower Windsor Township, York County, Pennsylvania

Marker Inscription

The Story

About 1730 the frontiersman Thomas Cresap settled along the Susquehanna on land that Maryland's Lord Baltimore claimed against Pennsylvania, making his fortified home a flashpoint in the bitter boundary dispute between the two colonies. In 1736 Penn's agents forcibly evicted him and burned his "fort," and Cresap moved west into Maryland, where he remained a restless figure in frontier affairs until his death around 1790. His stand gave the border quarrel one of its most colorful episodes.

Why it matters

The clash over Cresap's fort dramatizes the messy, sometimes violent work of drawing colonial boundaries — disputes eventually settled by the surveying of the Mason-Dixon Line.

Captain Thomas Cresap (1703-1790) - PLAQUE

Lower Windsor Township, PA · est. 1924

When Thomas Cresap settled here in 1730, the border between Pennsylvania and Maryland was undrawn and hotly contested, and he claimed these lands for Lord Baltimore against the heirs of William Penn. His stubborn defense made him a flashpoint of "Cresap's War," the frontier feud over the disputed boundary. In 1736 Pennsylvania forces burned him out of his fortified log house and hauled him off a prisoner to Philadelphia.

Springetsbury Manor

Wrightsville, PA · est. 1950

In the colonial era the Penn family, as proprietors of Pennsylvania, reserved for themselves vast private estates carved from the province they governed. Springetsbury Manor, stretching from the Susquehanna some eighteen miles westward and about three miles to each side of this road, was the largest such reserved holding of the Penns in the colony. These proprietary manors let the founding family profit as landlords over the very land they administered.

Pennsylvania Rifle

Lancaster Township, PA · est. 1947

The long, slender flintlock famous as the "Kentucky Rifle" was in truth a Pennsylvania creation, refined by German-American gunsmiths around Lancaster during the 1700s. Accurate at ranges that stunned European soldiers, it became the tool of the frontier hunter and, later, a weapon of legend in the Revolution — a piece of American craftsmanship carried far beyond the state that perfected it.

Andrew Ellicott

Lancaster, PA · est. 1999

Andrew Ellicott was one of the young republic's most accomplished surveyors, astronomers, and mathematicians, helping fix the boundaries of New York, Pennsylvania, and the new federal capital at Washington, D.C. While living in Lancaster and serving the Pennsylvania Land Office, he tutored Meriwether Lewis in surveying and celestial navigation in 1803—skills Lewis would soon carry across the continent on his expedition west.
