Fort Deshler

Whitehall, Lehigh County, Pennsylvania

Marker Inscription

A substantial stone structure, used as a military post and as a refuge for settlers against attack, was nearby on the north bank of Coplay Creek. It was built in 1760 by Adam Deshler, a native of Switzerland. Remaining in his family for several generations, the building was owned by the Coplay Cement Company after 1899 and stood until about 1940.

The Story

On the north bank of Coplay Creek, Swiss immigrant Adam Deshler raised a sturdy stone house in 1760 that doubled as a fortified refuge during the dangerous years of the French and Indian War. Frontier families sheltered behind its walls when raids threatened the scattered settlements of the Lehigh Valley. The building outlived its garrison days by nearly two centuries, passing through the Deshler family and later the Coplay Cement Company before finally coming down around 1940.

Why it matters

Fort Deshler recalls the perilous frontier of colonial Pennsylvania, where ordinary stone farmhouses became lifelines for settlers caught in the wider imperial struggle for the continent.

Trucker's Mill

Slatington, PA · est. 1952

A sawmill standing here before 1755 turned the forests of the Lehigh Valley into lumber for a growing frontier. When the French and Indian War set the backcountry ablaze, the sturdy mill — also called Kern's Fort — became a defensive station and shelter for troops. Sitting at the crossing of two pioneer roads, it commanded a position of real military value in a dangerous borderland.

Fort Allen

Franklin Township, PA · est. 1947

In 1756, as the French and Indian War set the Pennsylvania frontier ablaze with raids, the province built a chain of stockaded forts to shield its scattered settlers. Fort Allen was one link in that defensive line, raised on the site of present-day Weissport along the Lehigh. Benjamin Franklin himself oversaw the construction of forts in this region during that anxious winter, when the backcountry felt anything but safe.

Fort Allen Well

Weissport, PA · est. 1971

In 1756, as the frontier violence of the French and Indian War pushed Pennsylvania settlers into panic, the colonial government threw up a chain of defensive forts along the Blue Mountains. Fort Allen at present-day Weissport was among them, and its construction was overseen personally by Benjamin Franklin, then a colonial official who marched into the backcountry to organize the province's defenses. The fort itself is long gone; only its stone well survives, restored and tucked behind the houses across the road.

Gnadenhuetten

Lehighton, PA · est. 2005

In 1746 Moravian missionaries established Gnadenhuetten, a mission town meant to shelter a growing community of Mohican and Delaware converts and the first European settlement in what is now Carbon County. As the French and Indian War engulfed the frontier, tensions boiled over, and on November 24, 1755, the settlement was attacked and burned in a raid encouraged by the French. The victims were laid to rest in what is now the Lehighton Cemetery nearby.
