The castle of Brina is located on the left slope of a hill in the lower Val di Magra, along the ridge between Falcinello and Ponzano Superiore, within the district of Sarzana and on the border with Santo Stefano di Magra. The original part of the castle could date back to the 11th century. It was first mentioned in a sales contract on May 25, 1055. The houses, the lands and the castle’s walls were mentioned in a sales document on June 14, 1078, in which Pellegrino de Bruciore sold all his belongings and the lands outside the walls of the defensive fortification of Brina to the bishop of Luni.
During the 14th century, the castle was torn down, not by war, but as a result of a systematic destruction. This is confirmed by the ruins of the buildings, which show signs of having been destroyed using picks. The tower was torn down through the mining technique, that is to say by substituting a line of rocks at the base of the building with wood and setting it on fire.
The castle is in ruins but it has been made safe and strengthened after a recent restoration.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.
