Saint-Lizier Cathedral can refer to either of the two former co-cathedrals of the town of Saint-Lizier, Notre-Dame Cathedral (Cathédrale Notre-Dame-de-la-Sède de Saint-Lizier) and St. Lizier's Cathedral (Cathédrale Saint-Lizier de Saint-Lizier), dedicated to Saint Lycerius.
Saint-Lizier falls into two quite separate parts, each with its own cathedral. The lower part contains the old village around the Cathedral of Saint Lizier while the upper part, surrounded by ancient fortifications, includes the Bishop's Palace.
St. Lizier's Cathedral features an octagonal tower and attractive cloisters with a balcony and interesting carved stone decorations at the top of the columns. There are a large number of ancient (11th century) frescoes inside the cathedral.
The cathedral is part of the UNESCO World Heritage Site of Routes of Santiago de Compostela.
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.
