Arnes is a synonym for an island in river Thjorsa, a community centre, and a hamlet which has developed around the school and the community centre during the last few decades. The present name of the district is derived from the name of the island, which was a part of the western bank of the river until it carved its way around it.
The ancient spring parliament was held on the island and there are numerous ruins of a circular tribunal and dwellings still visible and the topographical names Parliament Mound and Gallow Cliffs nearby.
The island has been eroded and does not offer any grazings. The ruins on the island have been declared inviolate. An interesting and beautiful side road passes through the hamlet north of the low mountain Midfell and joins the main road just opposite the island Hagaey.
