A colonial blockhouse built in 1745, Fort Zeller served as a place of refuge during indian raids in the mid-eighteenth century.
According to "Frontier Forts of Pennsylvania", Christine Zellers, probably in 1756, while alone at the fort saw three prowling Indians approaching and heading for a small hole in the cellar. She quickly descended the cellar steps and stationed herself at this window with an uplifted axe. The head of the first Indian protruded through the hole, when she quickly brought down the weapon with an effective blow. Dragging the body in, she disguised her voice and in Indian language, beckoned his companions to follow,which they did and were all dispatched in the like manner.
