Elewijt Castle originates from the 11th century when there was a wooden fortification. The stone castle was erected around 1300. The castle is also known as Rubenskasteel because it was owned by Peter Paul Rubens from 1635 to his death in 1640, and features in some of his paintings. In 1792 the castle was converted into a state prison. The castle is now privately owned and not open to the public.
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.
