The oldest part of the church is the tower, dating from the middle of the 13th century. The nave is from the beginning of the 14th century, while the choir dates from the middle of the same century. There was an earlier church on the same spot, elements of which have been incorporated as building material in the presently visible church. The church is richly decorated inside with frescos dating from the Middle Ages. They depict different Christian motifs. Of the church fittings, the baptismal font (second half of 12th century) and triumphal cross (middle of the 13th century) are both medieval.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
