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 Peace Palace (Vredespaleis) is an administrative building and often called the seat of international law because it houses the International Court of Justice (which is the principal judicial body of the United Nations), the Permanent Court of Arbitration, the Hague Academy of International Law, and the extensive Peace Palace Library. In addition to hosting these institutions, the Palace is also a regular venue for special events in international policy and law. The Palace officially opened on 28 August 1913, and was originally built to provide a symbolic home for the Permanent Court of Arbitration, a court created to end war which was created by treaty at the 1899 Hague Peace Conference.
