Skriðuklaustur is an ancient manor estate in Fljótsdalur. From 1493 - 1552 a monastery operated there. In the years 2002 - 2012 an extensive archaeological excavation took place on the cloister ruins which are now open to visitors. The writer Gunnar Gunnarsson (1889 - 1975) bought Skriðklaustur in 1939 and built a large house there designed by the German architect Fritz Höger. The writer moved to Reykjavík in 1948 and donated Skriðuklaustur to the Icelandic nation. In 2000 the institute of Gunnar Gunnarsson resumed operation in Skriðuklaustur as a centre of culture and history. In the summertime, Skriðuklaustur comes alive with various exhibitions, cultural happenings and guided tours for visitors around the writer's house and the archaeological site.
