buildings that still stand today were constructed. Ceiling frescoes in the Marble Hall (1735) and the library (1740) were executed by Paul Troger, while those on the grand staircase were by Bartolomeo Altomonte. The summer refectory contains 19 pictures by Kremser Schmidt. The finance for these lavish works came principally from the abbey's copper mines in the Radmer (Styria) and the brass foundry at Reichraming (Upper Austria). After the difficulties of the anti-monastic policies of Emperor Joseph II and of the Napoleonic wars, the abbey gradually regained its strength through the 19th century, until the time of Abbot Theodor Springer (1920–58), who not only brought the abbey safely through the economic crisis after World War I but also through the National Socialist period and World War II without its being dissolved, as so many other monasteries were. Since the war more renovations have taken place both to the Pilgrimage Church and to the structure of the abbey itself. Besides the major works of art and architecture mentioned previously, there are also the Romanesque Knights' Chapel (Ritterkapelle), the picture gallery, and the garden, which contains about 110 different types of rose, mostly historical. Since 1625 the abbey has been a member of the Austrian Congregation, now within the Benedictine Confederation.
