A great abbey church named Belli Locus dedicated to the Holy Sepulchre was founded in the early 11th century by Fulk Nerra, Count of Anjou, who is buried in the chancel. In 1011 Pope Sergius IV donated some relics of Saints Chrysanthus and Daria and Fulk himself a piece of the Holy Sepulchre he stole from his visit to Jerusalem to the abbey. The pope settled a dispute over the abbey's consecration with the Archbishop of Tours by himself sending a legate to consecrate it. The abbey was closed down in 1791.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.
