Sletringen Lighthouse, Concrete lighthouse in Frøya, Norway
Sletringen Lighthouse is a concrete tower on Frøya island with a cylindrical shape, painted red with white horizontal bands and a white base. The structure rises prominently above the surrounding landscape and serves as a navigation aid for maritime traffic in the area.
The lighthouse was built in 1899 as part of Norway's maritime infrastructure development. The structure transitioned from manual operation to automated systems in 1993, reflecting changes in navigation technology and staffing practices.
The lighthouse stands as Norway's tallest navigational structure, representing the nation's commitment to maritime safety along its extensive coastline.
The tower sits on an exposed headland accessible on foot from nearby roads. Visitors should prepare for windy conditions and changeable weather typical of coastal locations in this region.
The tower contains two separate light sources: the main beacon at 46 meters and a secondary light positioned 31.5 meters up the structure.
