Name

The name Krýsuvík means "bay of Krýsa," a folk tale figure from the area. ''Krýsa'' was an old woman who, together with her cousin ''Herdís,'' could use witchcraft. They had a discussion about the borders of their respective lands; one wanted to cast a spell so that all the fish in a nearby lake would be hairy, the other intended to bring up a storm and let all fishermen die. The dispute ended with the death of both of them. The folk tale says that they were buried side by side, and the place of the graves is still known to locals. The ''Ögmundarhraun'' lava flows which were emitted by the nearby Krýsuvík volcanic system in the 12th century, destroyed the Krýsuvík farm, which was located at the coast, and filled up the bay.Snæbjörn Guðmundsson: Vegavísir um jarðfræði Íslands. Reykjavík 2015, p. 24


History

There were farms in the vicinity from the Middle Ages till 1945. After the eruption known as the
Krýsuvík fires The Krýsuvík fires were a period of volcanic activity in a fissure swarm known as Krýsuvík (volcanic system), Krýsuvík (:is: Krýsuvíkureldar) on the Reykjanes peninsula. The fires started in the middle of the 12th century, probably in ...
in the middle of the 12th century, probably in 1151-1188, the main farm was transferred to a place under the mountain Bæjarfell. The name Krýsuvík was still used for the farm, though the buildings were at a distance of some kilometers from the sea. The farm had a reputation for being very rich till the end of the 19th century. Being near the sea, the farm had additional income from fishing and hunting. Commerce was also done, because the farm was a junction of old trails from the north to the south coast. Also the sulfur of the nearby geothermal areas was mined and exported.Vegahandbókin. Ferðahandbókin þín. Landmælingar Íslands og Vegahandbókin. 2014, p. 213 However, Krýsuvík was too far away from upcoming industry and commerce and therefore abandoned in the middle of the 20th century. Árni Gíslason, one of the richest people in Iceland in the 19th century, lived in Krýsuvík. In 1949, a new farm (Fjósið) was constructed near the maar Grænavatn, but for many reasons, never used much as such. As all the estate farms in Iceland, Krýsuvík had its own small
