Château du Taillis was built in 1530 by Jehan du Fay du Tailly in an Italian Renaissance style on the foundations of a fortified mansion of the 13th century. It was extended between the 17th and the 18th century. The castle has a beautiful large park with a chapel dating from the 16th century.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.
