Solid church in granite built inside the medieval town walls. Work began in 1488 under the guidance of Biscay master Tomé de Tolosa, and using parts of a primitive Romanesque chapel (remains are visible in the north side); it pursued slowly, until the completion of the tower of the main façade in 1556. Important architects involved in the construction include João de Tolosa and Pero Galego. Inside, the building is a basilica with main nave and two aisles, and is notable for its inlaid ceiling (1565) showing oriental influences. The Mareantes Chapel, built by the corporation of seafarers, is one of the earliest renaissance works in Portugal. The church was classified as a National Monument on June 16, 1910.
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.
