The religious history of the place started in 1716 when a man called Franz Obermayr put up a Pietà on the weather cross which was standing on the top of the hill. Already in 1720 pilgrims started to climb the hill and a wooden chapel was built. In 1742 the erection of the Pöstlingberg church started and opened 6 years later.

The pilgrimage church, dedicated to the Seven Sorrows of the Virgin Mary and perched high above the roofs of the city, is the landmark of the Upper Austrian capital.
