Santa María da Armenteira Monastery belongs to the Cistercian order and was founded by the knight Ero de Armenteira in 1168. It has a square cloister, a kitchen, and a tower, all in the 18th-century Baroque style. The monastery was abandoned after the sale of church lands in 1835. The church has a floor plan in the shape of a Latin cross, three naves and three semicircular apses. The central nave is crowned with a pointed barrel vault, and the side naves with groin vaults. The transept has a vault raised on Mudéjar-style pedentives. On the façade, the 12th-century rose window is of particular interest. The whole complex has today been rebuilt thanks to the Association of Friends of the Monastery of Armenteira.
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.
