Located in the French town of Saumur, in the Maine-et-Loire departement, the Chateau de Saumur was originally constructed in the 10th century by Theobald I, Count of Blois, as a fortified stronghold against Norman predations. It overlooks the confluence of the Loire and the Thouet. In 1026 it came into the hands of Fulk Nerra, count of Anjou, who bequeathed it to his Plantagenet heirs. Following its destruction in 1067, the château was rebuilt by Henry II of England in the later 12th century.
In the early part of the 13th century, Philip II of France made Saumur part of his royal domain. The page for September in the Tres Riches Heures du Duc de Berry depicts the Chateau as it looked in 1410. It changed hands several times until 1589 when the Protestant King Henri IV (of France and Navarre) gave the castle to Duplessis-Mornay.
