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:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
