The Story
Carved from Lancaster County in 1750, Cumberland County once stretched all the way to Pennsylvania's western frontier, a vast gateway for settlers pushing toward the Alleghenies. Its seat, Carlisle, was founded the following year and became a crucial staging point on the roads leading west. In the colonial and early national decades, this was the edge of English America, where the Great Wagon Road funneled families toward the interior.
Why it matters
As a launching point for westward migration, Cumberland County shaped the movement of people and goods that carried American settlement across the mountains.

Simpson Ferry Road
Mechanicsburg, PA · est. 1954
Laid out around 1792, Simpson Ferry Road ran from Michael Simpson's ferry crossing on the Susquehanna River inland toward Carlisle, tracing at this point a route later remembered as Simpson Street. In the young republic it was a vital artery for settlers and travelers pushing toward the western part of the state.
Harrisburg
Wormleysburg, PA · est. 1947
Harrisburg began as Harris' Ferry, settled in the early 1700s by John Harris Sr. at a strategic crossing of the Susquehanna River. His son laid out the town in 1785, and in 1812 it became Pennsylvania's capital, cementing a role as a crossroads of travel and trade it had already held for generations. For over two centuries the site has funneled people and commerce through the heart of the state.
Harris' Ferry - PLAQUE
Harrisburg, PA · est. 1915
On the banks of the Susquehanna here stood the landing of Harris' Ferry, first granted to John Harris in 1733 and for half a century the name by which the future Harrisburg was known. It was among the most important crossings in early Pennsylvania, funneling settlers, traders, and pack trains westward into the interior and on toward the Ohio Valley. From this modest ferry grew the city that would become the state capital.
Episcopal Square
Carlisle, PA · est. 1949
In 1751, when Carlisle was still a raw county seat on Pennsylvania's western frontier, the Penn family set aside this square for the Church of England, and the first church building rose the following year. St. John's Episcopal congregation has worshipped on the ground ever since, an unbroken thread of community life stretching back before the Revolution. The grant reflects the proprietors' careful planning of Carlisle as an ordered outpost of colonial society.
