Schloss Seggau is located on a wooded hill overlooking the town of Leibnitz. The area around Schloss Seggau has been settled since at least the Roman era, as demonstrated by the impressive lapidarium which has survived from that period. The upper castle was built by the Archbishopric of Salzburg in the twelfth century as a base for missions and supervision and this original structure was expanded in 1218 by the bishops of Seckau. Over time, a total of three castles were built: Burg Leibnitz (belonging to the Archbishopric of Salzburg), the castle of the bishops of Seckau, and Schloss Polheim. The castles were completed in their present form under Bishop Johann Ernst, Count of Thun, in the latter half of the seventeenth century. Schloss Seggau was the residence of the bishops until 1786, after which it remained their summer residence until into the twentieth century.
Schloss Seggau now serves as a site for seminars and conferences with a hotel and a Schloss Cafe. The wine cellar is over three hundred years old and offers the opportunity for wine tastings and sales.
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.
