Green Bay Harbor Entrance Lighthouse is located roughly nine miles from the mouth of Fox River and marks the west side of the entrance to the dredged channel that leads to Green Bay. Construction for the lighthouse began in 1934. First a pier was constructed, then a lighthouse with a conical steel tower and circular base.
The light was activated in 1935 with a fourth-order Fresnel lens, which remained in operation until the station was automated in 1979.
An occulting red light and fog signal still operate today. You can check the current conditions at the light by clicking here.
