Coity Castle in Glamorgan, Wales, is a Norman castle built by Sir Payn 'the Demon' de Turberville, one of the legendary Twelve Knights of Glamorgan supposed to have conquered Glamorgan under the leadership of Robert FitzHamon (d. 1107), Lord of Gloucester.
The castle began as a late 11th-century ringwork. A rectangular stone keep and the main curtain wall were added by the Normans in the 12th century, under the de Turberville family. The three-storey keep was primarily a defensive structure.
Extensive reworking took place in the 14th century, when a domestic range was attached to the keep by the middle gatehouse. New stone vaults replaced the earlier timber floors. The central octagonal pier for the vaults is still prominent among the castle ruins. An adjoining chapel wing with a tall east window was added to the first floor at the eastern end of the domestic range in the 15th century.
The Gamage family held Coity until the death of John Gamage in 1584. The castle was abandoned around the 17th century. The castle was sold in the 18th century to the Edwins of Llanharry. Through the Edwins, the Coity lordship passed to the Earls of Dunraven.
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.
