The tower's original 4th-order Fresnel lens was replaced by a modern LED beacon in 2014.
Its skeletal design was specifically engineered to withstand high wind loads near the open lakefront.
The structure functions as a range light, meaning mariners align it visually with a forward light to stay within the safe channel.
It is painted a distinct white with a black lantern room to ensure visibility against the coastal horizon.
The base of the tower is anchored into a concrete foundation designed to resist erosion from the surrounding canal shoreline.
The Sturgeon Bay Canal Rear Light is a functioning 1903 steel skeletal lighthouse tower standing 104 feet tall. It serves as the rear range light for the Sturgeon Bay Ship Canal, working in tandem with the North Pierhead Light to guide vessels. The structure is one of the few remaining examples of a skeletal lighthouse designed for inland waterways. It is listed on the National Register of Historic Places and remains an active aid to navigation maintained by the U.S. Coast Guard. The light is situated on the grounds of the Sturgeon Bay Canal Station, which houses the oldest Coast Guard station on the Great Lakes. Visitors can view the tower from the exterior, as the interior is typically restricted for safety and operational reasons. The site provides a clear view of the canal entrance, which connects Green Bay to Lake Michigan.

Stay on designated paths as the facility is an active military and navigation site.
Visit during the fall months to avoid heavy lake flies and enjoy clearer atmospheric conditions.

The grounds are generally accessible, but the lighthouse itself is closed to the public year-round.
Maintain a respectful distance from active Coast Guard operational buildings and do not trespass on gated areas.
