The medieval Kienburg castle was located between Huben and St. Johann im Walde, in the municipality of Matrei. Its name derives from the old German term for 'kühn', that's to say bold, or from Archbishop Erich Kuenburg, one of its owners. It is a hill castle, located in the forest above the Iseltal valley and mentioned for the first time around 1000 AD.
The castle had a key position in the trade of the Iseltal, Defereggental and Kalsertal valleys. Once, the mighty Earls of Lechsgemünde inhabited the castle, in the following centuries, it was witness and centre of fight and devastation. Among the owners there were the Bishopric of Salzburg and Knight Earl Christoph von Kienburg, its last inhabitant when it was destroyed by a fire in 1579. In 1945, an American aerial bomb destroyed most of the still existing walls.
Currently, the Kienburg Castle Ruin is being renovated: It is in private hands, the surrounding is a restricted archaeological area.
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.
