Fort Gratiot light was built in April 1829. It was situated north of an older tower light that has collapsed into the St. Clair river after a violent storm. The tower was constructed of brick to the height of 65 feet. In 1862 the height was increased to 82 feet to match the focal point of a new 4th order Fresnel lens.
