Fort Pitt blockhouse

The blockhouse at Fort Pitt in Pittsburgh, Pennsylvania, is the only surviving structure from this eighteenth-century fort. It is now part of the Fort Pitt Museum.

During the French and Indian War (Seven Years' War), British forces captured the French Fort Duquesne at the forks of the Ohio River. They built their own fort, Fort Pitt, which they named for Britain's Secretary of State for the Southern Department, William Pitt (the Elder). They also named the surrounding area Pittsburgh.
