The Kollegienkirche was built between 1694 and 1707 for the local Benedictine university founded in 1622. The university was disbanded in 1810 but reopened in 1962 as part of the University of Salzburg.
Certainly the largest and best Salzburg church designed by Erlach (who also built the Holy Trinity Church and renovated the Franciscan Church), the Collegiate Church is also one of the most celebrated Baroque churches in all of Austria.
The church is built on a modified Greek cross plan with a unique convex facade. Inside, the high altar by Anton Pfaffinger (1740) incorporates classical columns representing the Seven Pillars of Wisdom. Altar paintings are by Johann Michael Rottmayr.
Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
