The famous Calvary at the Haydn church was built by the Franciscan lay brother Felix Niering in the years from 1701 – 1707. The Calvary in Eisenstadt follows the pattern of the Calvary in Maria Lanzendorf in Lower Austria. Steps and dark hallways lead through an artificial mountain made of rocks and pass by small niches, grottos and tiny chapels portraying scenes of the Passion of Christ. At the east side of the Calvary, there is the Chapel of Mercy. It contains a miraculous image that is visited by many pilgrims every year. The Chapel of Mercy already forms part of the Calvary. Originally it had been built as Mount of Olives Chapel. After the Statue of Mercy had been transferred from the church in Grosshöflein the chapel was re-consecrated as Chapel of Mercy. https://www.eisenstadt-leithaland.at/en/sightseeing/sightseeing/calvary
