The Château de Dourdan was built at the request of Philip Augustus in the 1220s in the place of a wood structure. The castle became the property of Jean de Berry in 1385. It was besieged during the French Wars of Religion. Among some of the notable personages who resided in the castle were Philip IV of France's daughter-in-law, Joan II, Countess of Burgundy, detained there from 1314 to 1315 in relation to the Tour de Nesle affair, and La Hire, one of Joan of Arc's comrades-in-arms.
At the end of the 17th century, the Château de Dourdan was given to the Duke of Orléans who turned it into prison. The donjon was used as a prison until 1852. It now houses a museum of local history.
The fortification is characteristic of the military architecture of this period. It is built on a square pattern, with towers at three of the corners and an isolated donjon at the fourth. The walls are punctuated by towers in the middle of each side, and two, on the east side, flank the gatehouse. A deep stone-lined dry moat follows the outline of the castle.
The donjon, the major defensive component of the castle, measures approximately 30 metres in height and 13.6 metres in diameter. It is the typical of the donjons being built by King Philip II Augustus of France at this time, like at Rouen and other French nobility throughout the 13th century.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. 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.
