The Piarist Church, also known as the Church of Maria Treu, is a Baroque parish church of the Order of the Piarists in Vienna. The church has eight chapels and is decorated with frescoes made by Franz Anton Maulbertsch in 1752–53. Commissioned by the Piarists, Haydn’s Missa in Tempore Belli (Mass in Time of War, sometimes known as Kettledrum Mass) was first performed here on 26 December 1796. The Piaristenkirche was elevated to the rank of Basilica Minor in 1949.
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.
