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:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
