Pilgrimages here began around 1100 and increased after the "blood miracle" that is reported to have happened in about 1310. The main objects of veneration are Saint George, a Gothic Pietà sculpture from about 1415 and the reliquary of the Holy Blood. The present Baroque church, dedicated to Saints George and James, was built after the 1705 fire on the site and to the approximate ground plan of the old church. St. Georgenberg remained a place of pilgrimage even after the monks moved to the city in the valley below. The new building was finished in 1735, with further alterations in 1863 (frescoes) and 1866.
