The Château Moncade is a ruined castle in the commune of Orthez in the Pyrénées-Atlantiques département. Construction of the castle was started in 1242 by the Gaston VII, Viscount of Béarn (the keep, known as the tour de Moncade) taking advantage of the absence of Edward III. When the King returned, Gaston was imprisoned and had to swear allegiance before being released. He subsequently reneged.
It was the residence of the Kings of Béarn when their capital was Orthez. Standing on top of a hill above the town, it afforded views of the surrounding county over a radius of more than 30 kilometres. The central tower was surrounded by high curtain walls and moats up to 15 metres deep. Entry was by a drawbridge.
In the 14th century, Gaston Phébus, Count of Foix, altered it between 1368 and 1375. The castle was burned during the Wars of Religion in 1569. It was sold during the French Revolution to dismantlers who largely demolished the curtain wall.
The only remains are the keep (in a good state of preservation), the moats (in course of restoration) and remnants of the curtain wall. The castle is open to the public (paying) and contains, among other items, a model of the site.
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.
