The Château de Montluc, named after its famous owner Blaise de Monluc, is located in Estillac, in the French department of Lot-et-Garonne. Built in the 13th century, it was expanded in the 16th century in a Renaissance style by the Mondenard family. Blaise de Monluc inherited it in 1544 and undertook major works, including the addition of defensive bastions inspired by Italian fortifications. He also planned a funerary chapel for himself. The castle was modified to withstand the religious wars but was partially demolished in 1793. Blaise de Monluc lived here to write his commentaries but died in 1577, leaving the estate to his grandson. Over the centuries, the castle changed hands and was classified as a historic monument in 1958. Its architecture features a trapezoidal plan with an almost triangular interior courtyard.
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.
