Adria Cathedral (Duomo di Adria) replaced the much older former cathedral nearby, dedicated to Saint John, which continues in use as a parish church. The new cathedral, dedicated to Saints Peter and Paul, was built in the early 19th century over a 14th-century church. When works were undertaken in 1830 to investigate the stability of the foundations, a Byzantine crypt and frescoes were discovered.
The cathedral also contains a Byzantine bas relief of the 6th century, a Byzantine altar and crucifix, and in the sacristy some magnificently carved cupboards by Jacopo Piazzetta from the Charity School of Venice.
Behind the building a replica of the Grotto of Lourdes was constructed in the 1930s, which still attracts many visitors.
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.
