The Château-sur-Epte Castle construction was begun in 1097 by William Rufus, King of England, to reinforce the frontier of Epte. The castle occupied a site on the border between the Duchy of Normandy and the Kingdom of France. In 1119, it was besieged by Louis VI of France and reinforced by the Plantagenets in the 12th century and again during the Hundred Years' War.
In the 12th century, it was restored and reinforced by Henry II of England (keep and entry). Other works were carried out in the 14th century. In 1437, the château was captured by John Talbot, 1st Earl of Shrewsbury. The castle's role declined in the 16th century and it was ordered to be dismantled by Mazarin in 1647. Transformed into an agricultural centre under the Ancien Régime, it comprised a motte with a stone keep, a lower court linked to the motte and defended by a curtain wall flanked in the east and west by two fortified gateways (14th century), a drawbridge and, in the lower court, a medieval barn, a 17th century corps de logis and a dovecote. The condition of the site deteriorated.
The ruins are private property. It has been listed since 1926 as a monument historique by the French Ministry of Culture.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
