San Nicandro castle as we see it today dates from the 15th century although it was built on the site of a much more older fortress dating from the Norman and Swabian periods.
The castle is trapeze shaped with four corner towers, and was renovated during the 17th century. On the north side there are two square towers, one of which is one of the original towers, while on the south side there are two round towers built by the Aragonese which are behind the church.
The castle, which was actually built as a mansion, was the usual residence of the Della Marra and all the vassals of San Nicandro Garganico until the time of the Cattaneo Princes. In the 16th century the castle was integrated with the gateway to the east and the lodge was built that connected the castle with a large palace built between the door and the walls of the castle.
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.
