The lighthouse was established in 1782 atop the "French Castle", a structure still located within Old Fort Niagara. The current tower was first lit in 1872, having been removed from the French Castle to allow for more room for officer's quarters. The light was deactivated in 1996, having been replaced by a light beacon at the US Coast Guard Station Niagara.
The foundation was natural/emplaced and the lighthouse was constructed out of limestone with a brick lining. The tower is octagonal in shape with a black lantern. The original lens was a fourth order Fresnel lens installed in 1859
