The fort was built by Adam Deshler, who was employed during the French and Indian War furnishing provisions for provincial forces.[2] It was actually a fortified stone blockhouse, 40 feet (12 m) long and 30 feet (9.1 m) wide, with walls 2.5 feet (0.76 m) thick, that was also as Deshler's home. Adjoining the building was a large wooden building, suitable as barracks for 20 soldiers and for storing military supplies.[1]
There appears to be no evidence that the fort was either garrisoned with provincial troops or served any military purpose beyond functioning as a place of refuge and rendezvous for settlers of the region.[3]
The fort remained in the Deshler family until 1899, when the building and its remaining 151 acres (0.61 km2; 0.24 sq mi) of property were sold to the Coplay Cement Company for $100,000.[4]
The historian Charles Rhoads Roberts, in his 1914 History of Lehigh County Pennsylvania and a Genealogical and Biographical Records of its Families, wrote the following about Fort Deshler:
This old stone mansion, the only building standing in Lehigh County which was used as a fort in the colonial period, should by all means be preserved and marked as a historic spot, not only as a memorial to the pioneers of this location but also as a reminder to the coming generations of the hardships which their staunch and sturdy ancestors were compelled to undergo.
