Built by Vauban in 1681 and fortified by Napoleon III, the fortress dominates the city of Villefranche-de-Conflent with its ramparts, counterscarp galleries, bastions, chapel, archaeology and caving museum and a 734 steps underground staircase. The ramparts - major site built by Vauban- are registered on the list of the Unesco World Heritage.
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.
