History

The lighthouse was first lit in 1844, and listed as a protected site in 1999. At an elevation of 78.2 metres (257 ft), the lighthouse has the highest elevation of all the lighthouses in Norway. Originally, the lighthouse had a twin lighthouse located about 100 metres (330 ft) away. The twin lighthouses were used to distinguish it from other nearby lighthouses, but one of the two lighthouses was decommissioned in 1890. The functional lighthouse was automated in 1992 and de-manned in 2004. Since 2008, one of the lighthouse keeper's buildings has served as a tourist cabin. [1] [2] [3]

The 13.3-metre (44 ft) tall round stone building is painted red with a white trim. At the top, there is a 1st order Fresnel lens which emits three white flashes every 60 seconds. The light has an intensity of 986,200 candela, and it can be seen for a distance of up to 23 nautical miles (43 km; 26 mi). [3] [4]
