Former Augustinian canon's monastery in the Pöllauer Valley Nature Park in Eastern Styria, modelled on St. Peter's Cathedral in Rome.
Located in the center of the market town of Pöllau, this castle has its roots in a moated fortress from the 12th century. Its present baroque appearance reflects its later function as an Augustinian monastery. The baroque halls with their frescos and the former refectorium provide a venerable setting for cultural events and exhibits.
