Isle Au Haut Light, Maritime navigation point in Knox County, United States.
The Isle Au Haut Light is a white cylindrical structure made of granite and brick, standing on a conical granite foundation at Robinson Point. The tower sits on an elevated rocky outcrop and overlooks the waters below with solid, functional construction.
Built in 1907 by the United States Army Corps of Engineers on land purchased from Charles E. Robinson, the light was designed to guide vessels safely. It became part of a wider system of navigation aids that protected ships along Maine's rocky coastline.
The name Isle Au Haut comes from French and means "high island". Locals and visitors recognize this light as a symbol of safe passage along this stretch of the Maine coast.
The light operates with a solar-powered lens system that emits red flashes every four seconds, with a white sector marking the safe shipping channel. The island location means the site is exposed to weather and tidal conditions, so plan your visit accordingly.
The original light lens is a fourth-order Fresnel lens now housed in the Maine Lighthouse Museum in Rockland. The former keeper's quarters were later converted into a bed and breakfast that operated from 1986 to 2007.
