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 Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
