The Saint-Pierre Abbey in Airvault was initially a collegiate church of regular canons of Saint Augustine, founded around 990 by Audéarde, wife of Viscount Herbert I of Thouars. As the canons were lax in following the rules of the Order of Saint Augustine, the Bishop of Poitiers decided to send a monk from the Augustinian abbey of Lesterps in Limousin to reform it. Pierre de Fonte Salubri (of Saine Fontaine) was appointed the first abbot of Airvault in 1096 and died on August 7, 1110. He undertook the construction of the abbey church. According to the Chronicle of Saint-Maixent, the church was consecrated in 1100 but subsequently underwent modifications and additions.
After the creation of the diocese of Maillezais in 1317, transferred to La Rochelle in 1648, the abbey became dependent on it.
During the Revolution a road was pierced through the abbey separating the convent buildings of the abbey. Several buildings are still visible as the room called the 'vat', the 'prison' (fortified gate), underground rooms, the fourteenth-century chapel and especially the abbey house which has hosted since 1975 the municipal museum.
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.
