Established around 1157, Burg Güssing is the oldest castle in Burgenland. In 1524, Francis I, Batthyány (1497–1566) received it and the associated lands. The family still retains ownership.
Times changed and due to the modernization of warfare, the castle and fortress of Güssing slowly lost its strategic importance. In 1777 all guns were removed. Due to the high cost of maintenance and the introduced “roof tax” by empress Maria Theresia, there was a partial demolition of some of the castles fortifications.
In 1870 Prince Philipp Batthyány-Strattmann established a foundation for the preservation of the castle and monastery as an historic structure. However, in the years following World War I, foundation had lost most of its money due to inflation and the costs of war.
Today, the castle acts as a tourist attraction in addition to being an important historical structure. Theater performances, concerts and readings can be attended on the castle grounds during the summer months, and there is a family museum located within.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
