Fort de La Prée, built in 1625, is located near the eastern end of the Île de Ré. It was built by Royalist Army after they conquered the are from Huguenots during the Wars of Religion. They used materials salvaged from the remains of the Romanesque abbey of the Châteliers'.
The Duke of Buckingham ignored Fort de La Prée during his three-month siege of Saint-Martin-de-Ré in 1627. This neglect turned out to be a strategic error. Toiras managed to land troops there, and from there force the English to give up their siege and withdraw in defeat.
The fort subsequently underwent modifications under the oversight of several engineers: François Blondel (1664), Louis-Nicolas de Clerville (1672), Le Favolière, and finally Sainte-Colombe (1676). They added the gate, a barracks for 200 soldiers outside the walls, and some other outside works.
In 1685, Vauban, the preeminent engineer of the time, had François Ferr raze parts of the original fort, particularly the keep and the outworks that enclosed the entire fort.
The fort was later abandoned before being re-established in 1793. During the latter part of the 19th century, the external barracks were demolished. In 1875, the fort's covered way had sheltered passages added. The fort was decommissioned circa 1900.
During World War II the Germans occupied the fort. They added some blockhouses in the ramparts and on the seafront. From 1948, the fort became the administrative block for a development of vacations homes, but was closed in 1977.
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.
