Amendolea Castle has Norman origins, and it was enlarged subsequently in the late Middle Ages. It is now made up of two recognizable parts. One is the entrance of parallel piped shape, separated by a wall around the residential area. And the second is the rectangular hall of the latter, with very high walls and arched windows and small towers, one of which, isolated, served as a dungeon. With an irregular plan and strong walls, the Castle houses a chapel tower, built in the Norman age. At the second level of the tower, there is a small apsidal church with an entrance facing south, as in the Byzantine tradition. The castle was rebuilt several times, until the earthquake of 1783 that caused important collapses that could not be fixed.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.
