Château d'Hyères was one of the largest castles in Provence. The first mention of the castle dates from 1062. In 1524 and in 1536 the royal armies swept over Provence and Hyères castle was also besieged and conquered. It was reorganised by Charles I of Anjou in 1527 and ultimately dismantled by Louis XIII in a gesture of authority following the destructive religious wars. The castle has been labelled Historical Monument for its important architectural remnants. It offers a spectacular view onto the coast and the islands.
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.
