Sollerön (Swedish pronunciation: [ˈsɔ̂lːɛrˌøːn])[2] is the largest island in Lake Siljan and a locality situated in Mora Municipality, Dalarna County, Sweden.

[3][4] In the northern part of Sollerön, there are two large grave fields from the end of the Viking Age: one major at Bengtsarvet-Häradsarvet-Rothagen and one smaller at Utanmyra.

[4] Sollerögravarna, as the Viking grave area is known in Swedish, is thought to be so well preserved due to it being constructed of stone, rather than only soil.

Not all of the mounds are tombs, as many of the rocky areas are also the result of land clearing by farmers over a period of centuries.

The objects show similarities to those found in Viking graves around Scandinavia, for example in Mälardalen, Jämtland and Tröndelag.
