The Château de Sully-sur-Loire is a castle converted to a palatial seigneurial residence. The château is the seat of the duc de Sully, Henri IV's minister Maximilien de Béthune (1560–1641), and the ducs de Sully. It is a château-fort, a true castle, built to control one of the few sites where the Loire can be forded; the site has perhaps been fortified since Gallo-Roman times, certainly since the beginning of the eleventh century. In 1218, Philip Augustus constructed a cylindrical keep to the south of the present enclosure, of which buried foundations remain. Guy de la Trémoille, inheriting the fortress, undertook the construction of the Donjon, flanked by four towers, beginning in 1395. The smaller side was added in the 16th century to provide more agreeable accommodation. Sully bought the domaine in 1602, enlarged the park and the fortress; he strengthened the embankments of the Loire to protect the town from occasional flooding.
The Château de Sully-sur-Loire remained in the possession of the family until 1962 when it became a property of the Département du Loiret, and has since benefited from numerous restorations. It hosts a classical music festival each June. The château contains numerous tapestries, including a set of six 17th century hangings, paintings of Sully's ancestors and heirs, and 17th century furnishings. Here is also the tomb of Sully and that of his second wife.
Henri IV never visited, but Mazarin and Anne of Austria took refuge here in March 1652 during the rigors of the Fronde, France's civil war. Turenne stayed here the same year, before his defeat of the Grand Condé at the battle of Bléneau. Later, in 1716 and again in 1719 the château sheltered Voltaire, when he had been exiled from Paris for affronting the Régent, Philippe, duc d'Orléans.
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.
