Origin and history

The Devil's Tower of Orchies is the last vestige of the medieval fortified enclosure of the city, originally dating from the 13th century for its first version, although the present tower was rebuilt in the 15th century. It was part of a broader defensive system, including seven circular towers and five doors, as demonstrated by Deventer's 1545 plan. Its position at the western corner of the city made it a key work for the flanking of the ramparts, reinforced by water ditches.

The tower, of circular shape (7 meters in diameter), combines bricks and sandstones, with a round path, a watchtower, and fire burns adapted to the evolution of artillery. It also served as a prison in the 17th and 18th centuries, as can be seen from the graffiti and secure doors. After damage during World War I, it was classified as a Historic Monument in 1922 and restored, with a characteristic pepper roof.

Its history reflects the urban transformations: partial dismantling of the ramparts in 1826, integration into a private garden after 1918, and acquisition by the city in 2023. The tower preserves traces of its military uses (shooting nests, pigeon traps) and prisons, while illustrating the late defensive architecture of the Middle Ages in northern France.

The archival and iconographic sources (Deventer's plan, Napoleonic cadastre, 20th century photographs) document its evolution, from its role in Burgundy-Armagnac conflicts to its modern preservation. The removals visible on its walls mark the location of the old ramparts, now disappeared.

Classified for its heritage value, the tower remains a testimony of medieval defensive strategies and subsequent reuses (powder store under the Revolution, seed storage in the 20th century). Its current access to private property limits its visibility, but its ranking in 1922 guarantees its conservation.
