The Detroit River Light, also known as Bar Point Shoal Light, was first established as a lightship in 1875. The current sparkplug lighthouse was built in 1885. It sits in Lake Erie, south of the mouth of the Detroit River, 1.75 nautical miles (3.24 km; 2.01 mi) from land and about 20 nautical miles (23 mi; 37 km) from the Ambassador Bridge in the Detroit River. It is about 0.4 nautical miles (0.74 km; 0.46 mi) from the border with Canada, and just under 24 nautical miles (44 km; 28 mi) from Put-in-Bay, Ohio. Its original 4th order Fresnel lens is on loan to the Michigan Maritime Museum.
