Shortly after the year 1000, the bishops of Poitiers from the Isembert family, succeeding a family named Chauvigny, became lords of Chauvigny, and later barons from the 14th century onward. The baronial castle, also known as the Bishops’ Castle, was built in the 11th century by them. The quadrangular keep dates from the mid-11th century. Starting in 1397, Ithier de Mareuil, bishop of Poitiers from 1394 to 1405, added a second keep to the castle. Today, it hosts falconry shows.
The structure is a complex building, 80 meters long and 50 meters wide. It was frequently damaged and altered. By the late 17th century, it was already nearly abandoned.
You can still see a first enclosure with the original 11th-century entrance, a powerful 12th-century keep, the ruins of the 'new castle' built around 1400 (of which an impressive wall section remains, showing two stories of apartments) and the Saint-Michel chapel with its chapter room above. Access to the inner courtyards and buildings of the second enclosure (12th–16th centuries), including kitchens, bakeries, stables, a well, and a tunnel, was via a drawbridge. The castle chapel can be recognized by its vaulted ceiling bearing the coat of arms of Ithier de Mareuil.
The castle's current ruined state is due to its sale as national property during the French Revolution, after which the buyer turned the fortress into a stone quarry.
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.
