Fort Socoa in Ciboure was originally built under the rule of Henry IV to protect the region from the Spanish. Fort Socoa today was however built later under the reign of Louis XIII. In 1636, the Spanish army took the fort. A few years later, French sovereignty was restored.
In 1686, Vauban strenghtened the Fort and planned to build a pier to improve access to the Fort. The work of the fort was ended in 1698. The site housed a barracks and a chapel.
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.
