The first castle at Bonaguil was constructed after the middle of the 13th century, on a rocky spur, probably by Arnaud La Tour de Fumel. The single entrance to the keep, built above a natural cave, was a door six metres up, accessible by ladder.
It was entirely restructured at the end of the 15th and beginning of the 16th centuries by Bérenger de Roquefeuil, who added all of the defensive improvements of the end of the Middle Ages. The main danger at the end of the 15th century came from artillery. For protection, it was necessary to keep the enemy's cannons at a distance. An external wall, 350 m in length, was added to the castle, with lower curtains retaining a mass of earth which cushioned the artillery shots. This curtain wall was reinforced with small towers and equipped with guns.
When Bérenger died in 1530, the castle was not yet adapted for siege warfare, but it remained an imposing fortress. During the Wars of Religion, the two brothers fought in opposite camps, and the castle was taken in 1563. A first restoration took place in 1572. In debt, Antoine had to give the fortress to the lord of Pardhaillan in 1618, before being able to buy it back several years later.
François de Roquefeuil, a distant relative with some claim to the castle, took possession of it in 1656, kept and pillaged it for almost a year before abandoning it.
In the 18th century the earthworks to the west of the castle were enlarged and laid out as a large terrace and became a pleasant promenade. New apartments were built in the south, outside the inner wall, thus benefitting from a better outlook.
As well as being an impressive feat of military engineering, the Chateau Bonaguil is also a lovely chateau to visit.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
