Korshamn or Korshavn is a fishing village in the southern part of Lyngdal municipality in Agder county, Norway. The village is located on the island of Revøy, located at the mouth of the Grønsfjorden. Korshamn lies about south of the village of Austad. Korshamn Chapel is located in the village, serving the southern part of the municipality. Traditionally, a fishing village, it now caters to tourists, primarily through the "Korshamn Rorbuer" rental cottages.[2]
According to Snorre, in the year 1028, King Olaf II (Saint Olaf) made landfall on the island of Sælør, just south of Korshamn with thirteen ships and a thousand men. This event was commemorated by the erection of a sculpture of the king in central Lyngdal, revealed by King Olav V in 1983.
