Fort Franklin (Schuylkill County, Pennsylvania)
Fort Franklin was a stockaded fort constructed at the order of Benjamin Franklin in 1756, in response to a series of raids by Native American war parties on Pennsylvania settlements in late 1755, in particular the Great Cove massacre and the Gnadenhütten massacre. The fort was intended to provide protection for settlers' families during the French and Indian War, however the fort was poorly built, located in a sparsely populated area, and stood in a vulnerable position to the north of the Blue Mountain Ridge in Pennsylvania.
