Eagle Harbor Lighthouse in Eagle Harbor, Kewaunee County, United States | Lighthouse

The red brick Eagle Harbor Light Station sits on the rocky entrance to the harbor and is a working lighthouse as it guides mariners across the northern edge of the Keweenaw Peninsula. The original lighthouse, built in 1851, was replaced in 1871. The octagonal brick light tower is ten feet in diameter, with walls 12 inches thick and it supports a 10-sided cast iron lantern. The Lighthouse was manned by a head keeper and two assistant keepers.
This red brick lighthouse is still standing and is furnished with period furnishings and open to the public from mid-June to early October- 10 a.m. to 5 p.m. The lighthouse and museum complex is now owned by the Keweenaw County Historical Society.
The light has undergone several changes during the past years. In 1929 a radio beacon was added and in 1930 the light was electrified. In 1968 the original 4th order Fresnel Lens was replaced by a red and white aviation type beacon and in 1980 the light was automated. The Keweenaw County Historical Society is now the 22nd "Keeper of the Light."
The Coast Guard actually maintains the light, but volunteers in Eagle Harbor check constantly to be sure the auxiliary battery is keeping the light shining in case of a power outage.
