Eagle Bluff Lighthouse was constructed of cream city brick in 1868 at a cost of $1200. It marked a treacherous channel between Green Bay, Wisconsin and points north and east. The tower was 43 feet tall and the light from a wicked oil lamp shone 76 feet above the bay. There is still no electricity at this lighthouse today, but a solar panel on the top of the tower generates the power to run the Fifth Order Fresnel Lens that was put in place in 1918 to replace the original Third and a half order Fresnel Lens.. The light-keeper and families lived here from 1868 to 1926. The lighthouse is now restored and is a museum and is in the National Register of Historic Places.
