Origin and history

The castle of Arques-la-Battle, built in the 12th century on a pre-existing castral motte, was restored in the 14th and 15th centuries. It dominates a chalky spur between the valleys of Varenne, Bethune and Eaullne, offering a strategic position near the Channel. His history is marked by repeated seats, including that of 1053 where William the Conqueror besieged his rebellious uncle, Guillaume d'Arques, after a one-year resistance.

In 1123 Henry I Beauclerc, king of England and Duke of Normandy, rebuilt the stone castle, adding a Romanesque dungeon and a courting flanked by towers. The site was contested during the Anglo-French conflicts: taken by Geoffroy Plantagenet in 1145, taken over by Richard Cœur de Lion in 1195, then given to Philippe Auguste in 1204 after a long siege. During the Hundred Years' War, he resisted the English until the Treaty of Troyes (1420), before being taken over by Charles VII in 1449.

The castle played a key role in the Wars of Religion. In 1589 Henry IV won a decisive victory against the League despite a numerical inferiority of 7,000 against 30,000 men, thanks to his artillery. Abandoned militarily in 1688, it was partially dismantled in the 18th century, serving as a stone quarry. Ranked a historic monument in 1875, its ruins today bear witness to its defensive past and architectural transformations from the twelfth to the sixteenth century.

The square dungeon, erected around 1123 by Henri Beauclerc, is the heart of the castle. With massive foothills, it housed vaulted rooms, a well, an oven and a mill, with separate accesses to strengthen defence. A platform added at the end of the 15th century allowed the installation of guns. The main entrance to the northwest was protected by an artillery bastion built under François I, while a second gate, added in 1367 by Charles V, served the dungeon directly.

The deep ditches (15 to 20 metres), dug in the sixteenth century, and the courtine flanked by towers illustrate the successive adaptations to military progress. The site, sold as a national property in 1793, was preserved by an individual before being acquired by the state in 1860. Damaged during the Second World War by German occupation, it is now partially accessible, especially during Heritage Days.

Ranked in 1862, the castle is a remarkable example of Norman castral architecture, mixing Romanesque elements (donjon, courtine) and Renaissance adaptations (brick bastions). Its history reflects Franco-English conflicts, the wars of Religion and the evolution of siege techniques, from medieval assaults to modern artillery.
