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 Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
