Frösön

During most of recorded history Frösön was the regional centre of Jämtland, and it is the location of the Frösö Runestone, the northernmost in the world.

The Swedish composer Wilhelm Peterson-Berger had a summer house (and from 1930 a permanent home) on the island.

[1] In 1896 Peterson-Berger composed a set of piano pieces entitled Frösöblomster (Flowers of Frösön), and his opera Arnljot from 1910 is partly based on the runic inscriptions on Frösö Runestone.

From 1915 to 1988, Frösön was the location of Frösö sjukhus [sv], a state-owned psychiatric hospital tasked with caring for patients from all of Norrland.

The hospital's practices have later been questioned, and it is known to have anonymously buried at least roughly 50 of its patients.
