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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
