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:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
