Green Bay Harbor Entrance Light, Navigation lighthouse in Green Bay, United States.
Green Bay Harbor Entrance Light is a navigation lighthouse marking the western entrance to the dredged channel in Green Bay. The white conical steel tower with a cylindrical base rises approximately 72 feet (22 meters) and guides vessels into the harbor.
Construction began in 1934 using a pier foundation, and the light entered service in 1935 with a fourth-order Fresnel lens. The structure became essential to maritime operations in the bay.
The lighthouse keepers lived within the circular portion of the tower, working in two-week rotating shifts until the automation took place in 1979.
The light emits an occulting red beam visible from approximately 22 kilometers away and operates during the navigation season from April through November. Weather conditions and water state may affect visitor access to the structure.
During a severe December 1943 storm, four stranded lighthouse keepers faced starvation and received emergency supplies dropped by aircraft. This incident reflects the isolated and perilous conditions keepers often endured.
