Fort Frederick

Fort Frederick was built in 1756-57 by the colony of Maryland. During the French and Indian War in 1756 a £6000 appropriation was authorized by the Maryland Legislature at the request of Governor Horatio Sharpe to build a fortification on the frontier. The fort, named after Frederick Calvert, 6th Baron Baltimore, was completed the following year. "The fort's design, which was developed by Sebastian Vauban, a French engineer, is a large square with four diamond-shaped bastions. This is typical of 18th century fortifications. The fort is built of native sandstone."

The large stone fort was designed primarily as a place of refuge for area settlers. Between 1757 and 1758, small raids by Indians in nearby settlements, caused settlers in the surrounding countryside to flee eastward. At the same time men of the 60th Regiment of Foot and local militia soldiers garrisoned the fort. Ranging parties were sent from the fort to patrol the area and to deter if not prevent Indian raids.
