Neugebäude Palace is a large Mannerist castle complex in the Simmering dictrict of Vienna, Austria. It was built from 1569 onwards at the behest of the Habsburg emperor Maximilian II on the alleged site of Sultan Suleiman's tent city during the 1529 Siege of Vienna and apparently modeled after it.
It fell into disuse already in the 17th century and today stands in ruins. Under monumental protection since the 1970s, there are various efforts to restore the site.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
