The Cathedral of Mondoñedo was built in Romanesque and Gothic styles, mainly between 1219-1243. In the 18th century the facade was remodeled and the towers were added. It has three naves.
The polychrome statue in the high altar, called Nuestra Señora la Inglesa (the English Madonna) was rescued from St Paul's Cathedral in London during the Protestant Reformation of Henry VIII of England.
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.
