The Château de Belzunce is a ruined castle in the commune of Ayherre. Its construction dates from the 13th, 14th and 16th centuries
The castle has a trapezoidal plan flanked by four towers, representing two periods of construction, the Middle Ages and the 16th century. During the 16th century, it was redeveloped and finally ruined. During the French Revolution, it was sold as national property. It appears to have been used as a stone quarry. Neighbouring buildings and the outer fortifications survive only as foundations. The castle is notable for the Belzunce family. François de Belzunce was Bishop of Marseille at the beginning of the 18th century and the Marseille district of Belsunce was named by him.
It is privately owned and has been registered since 1992 as a monument historique by the French Ministry of Culture. It is not possible to visit the site, but it may be clearly seen from the road.
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.
