Dunyvaig Castle was built on top of an ancient fort or dun in the 12th century. Forfeited in 1493, the castle passed to the MacIans of Ardnamurchan. Afterwards the castle was leased to the MacDonalds, then the Campbells and back to the MacDonalds.
In the 17th century Dunyvaig was conquered several times by the English and Scottish armies. The castle was seized in 1647 by the Covenanters and passed into the hands of the Campbells of Cawdor, who held it until 1677, when Sir Hugh Campbell pulled down the castle and moved to Islay House.
Today all that remains of the castle are mainly the ruins of the sixteenth-century castle, although the site includes a thirteenth-century courtyard, and a fifteenth-century keep.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.
