Earliest record of the manor in Kankainen dates back to 1346, when there were at least two buildings in the village. First manor was built in the 15th century by Klaus Lydekesson Diekn, the commander of Turku castle. Next owners were the famous noble family Horn, who built the present stone manor castle in the mid-16th century.
The third floor was removed during the renovation in 1762-1763 and rebuilt again in 1935. In the 1990s Kankainen was donated to Åbo Akedemi (University of Turku). It’s a rare well-preserved manor representing the building style of Swedish medieval manor castles. Finnish National Board of Antiquities has defined Kankainen as national built heritage. Today it’s used as conference and festive center. Guided tours available for visitors.
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.
