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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
