The Cistercians, who settled in Schlierbach Castle on February 22, 1355, were asked to pray for the salvation of the Wallsee family.
Over the decades, they transformed this castle into a monastery. However, the turmoil of the Reformation also meant the end of monastic life for Schlierbach. The building fell into disrepair for 64 years, until 1620 when the Cistercians from Rein near Graz settled in the monastery. Her task was to take care of the pastoral care in the area and to let religious life flourish again.
A skilful policy on the part of those responsible meant that the Schlierbach Abbey has been able to exist without interruption since that time. From the last quarter of the 17th century, members of the Carlone family of artists from Northern Italy, together with abbots who were enthusiastic about building, renovated the monastery from the ground up. We can still admire what they planned and built in Schlierbach today.
