Mariahilferkirche (Our Lady of Succour Church) was a highly frequented pilgrimage church for many centuries. Its well-proportioned Baroque façade, its simple, elegant twin towers and its Renaissance nave make it one of Graz's finest religious buildings. The cloister's second courtyard has a former Minorite Brothers Renaissance refectory on the upper floor, which is known as the Minoritensaal and is now used as a concert hall.
