Laxá, a river flowing from Laxárdalur, which turns into Endalausidalur, reaching east into the Lón district. By the farm Hólmur at the top of Laxárdalur, in 1996, an old grave was discovered and excavations carried out near the ruins of a farm from the Viking age. This has given rise to theories that the site also contains the ruins of a temple or house of sacrifice; however, scholars differ in their opinions regarding this. Should the theory prove correct this would be the first time that a place of sacrifice from the Viking age is found in Iceland and indeed in the entire Nordic Region.
