Origin and history

The castle of Bethune has its origins in the second half of the 11th century with the construction of the dungeon, built for Gilon de Sully. This six-storey square dungeon, still visible at the southeast corner, is the oldest part of the monument. Its defensive architecture reflects medieval fortification techniques, with a staircase turret added later, probably at the end of the 15th century.

In the 15th century, around 1470, Marie d'Albret had the entrance work, the chapel and the body of the east house erected. The chapel, decorated with the figures of Marie d'Albret on its ceiling, bears witness to the symbolic importance of the place. The north wing, with a poterne and two archer towers, reinforces the defensive character of the whole, while the east wing, rebuilt in the Renaissance, becomes the main house body.

Between 1528 and 1545, a western Renaissance-style gallery was built for a second Marie d'Albret. Only two arches supported by pillars decorated with foliage and rinceaux remain today. Finally, around 1607, Maximilian de Béthune, Duke of Sully, built a terrace, marking the last major transformation of the castle. The trapezoidal plan, with its corner towers, recalls its origin as a medieval fortress, although parts of the south have been demolished.

Ranked a historic monument, the castle of Bethune illustrates the architectural evolution of the 11th to 17th centuries, mixing medieval defensive elements and Renaissance decorations. Legal protections, with registration in 1963 and partial classification in 1984, underline its exceptional heritage value.
