Situated to the west of Östersund, the largest island in Lake Storsjön, Frösön holds a rich historical significance. Named after the Norse god Freyr, the island, which served as the regional centre of Jämtland throughout much of recorded history, boasts the northernmost raised runestone in the world, known as the "Frösö Runestone”. Easily accessible by foot, car, or bus, the island is a short walk across the pedestrian bridge from Östersund. The renowned Swedish composer Wilhelm Peterson-Berger's enchantment with the island led to the creation of "Sommarhagen", now a museum and one of Östersund's most visited attractions.
