Fort Gratiot

Fort Gratiot was an American fort in Fort Gratiot, Michigan, in Saint Clair County, Michigan.

The Army constructed Fort Gratiot in 1814 as an outpost to guard the juncture of the Saint Clair River and Lake Huron. The fort took the name of the engineer supervising its construction, Charles Gratiot. Soldiers occupied Fort Gratiot until 1822 and then abandoned the fort. Lucius Lyon built Fort Gratiot Light north of Fort Gratiot in 1825-1829. The Army then returned from 1828.

Soldiers garrisoned Fort Gratiot intermittently through the American Civil War

The Army abandoned Fort Gratiot in 1879. It was not entirely shut down until 1895.

Pine Grove Park, in Port Huron, occupies part of the fort site. Historians suspect that some houses north of Pine Grove Park began as quarters for officers.
