On the grounds of Ft Mississauga the Mississauga Lighthouse once stood. It was built in 1804 and was the first lighthouse on the great lakes. The lighthouse was damaged in the Battle of Fort George, in 1813, and demolished by the British in 1814 when they built Fort Mississauga on the same site.

According to local legend the remains of the lighthouse were incorporated into the tower of the fort.

The lighthouse was tended by retired British Artillery Gunner, Dominic Henry, and his wife Mary.

In 1813 during the battle of Fort George Mary risked her life on the dangerous battlefield, bringing food and drink to the injured soldiers.

You'll hear her story when you enter the grounds of the fort.
