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.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
