First built in the 5th century, St. Simeon's Church has undergone alterations until as recently as 1980, and some find the terracotta and white exterior disappointing in comparison with the other churches. This 17th-century church is best known as the home of the mummified body of St. Simeon, one of Zadar’s patron saints.
The Chest of Saint Simeon is a rectangular cedarwood sarcophagus in the shape of a chasse, overlaid with silver and silver-gilt plaques, said to hold the relics of St Simon the God-receiver; it is located over the main altar in the Church of Saint Simeon. The chest, considered a masterpiece of medieval art and also a unique monument of the goldsmith's craft of the age, is one of the most interesting works in gold in Europe now under the protection of UNESCO. It was made by local goldsmiths to an Italian design between 1377 and 1380.
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.
