The castle was built between the 12th and 16th centuries.[1]
The Count of BloisThibaut V had the keep built around 1170. The Sainte-Chapelle was built between 1451 and 1493. The choir and the high chapel were built between 1451 and 1454, with the nave and the oratory between 1460 and 1464.
Together with the Château de Montsoreau (1453) and the Palais Jacques-Cœur (1451), Châteaudun's 15th-century additions are among the earliest examples of residences built essentially for leisure in France.[2]
François I of Orléans-Longueville[3] began construction of the north wing (the "aile Longueville") between 1469 and 1491. The upper floors were added by François II d'Orléans-Longueville and his descendants during the first quarter of the 16th century.
Today
The Longueville wing of the château
The castle includes:
a keep from the 12th century, 31 metres (102 ft) high (wall), 42 metres (138 ft) high (entire height), 17 metres (56 ft) in diameter
a chapel from the 15th century (one of the seven remaining Sainte Chapelle kind of chapels in France)
the Dunois wing from the 15th century
the Longueville wing from the end of the 15th century
The château overlooks the Loir River. Perched on a limestone outcrop, it shows its origins as a 12th-century fortress. Converted by Jean de Dunois during the Renaissance into a comfortable residence, the main body of the building is roofed in the gothic style. It still has, notably, a finely carved staircase from this period.
Renovated since the 1930s, the castle has been designated as a monument historique (historic monument) since 1918.[1]
