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:
Dunluce Castle is a ruined medieval castle located on the edge of a basalt outcropping in County Antrim, and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.
In the 13th century, Richard Óg de Burgh, 2nd Earl of Ulster, built the first castle at Dunluce. The earliest features of the castle are two large drum towers about 9 metres in diameter on the eastern side, both relics of a stronghold built here by the McQuillans after they became lords of the Route.
The McQuillans were the Lords of Route from the late 13th century until they were displaced by the MacDonnell after losing two major battles against them during the mid- and late-16th century.
Later Dunluce Castle became the home of the chief of the Clan MacDonnell of Antrim and the Clan MacDonald of Dunnyveg from Scotland.
In 1588 the Girona, a galleass from the Spanish Armada, was wrecked in a storm on the rocks nearby. The cannons from the ship were installed in the gatehouses and the rest of the cargo sold, the funds being used to restore the castle.
Dunluce Castle served as the seat of the Earl of Antrim until the impoverishment of the MacDonnells in 1690, following the Battle of the Boyne. Since that time, the castle has deteriorated and parts were scavenged to serve as materials for nearby buildings.
