The pilgrimage church prominently stands at the top of Purberg hill (469 m) in the northeast of Graz. It can be reached using the 216 steps of the Angelus stair. The Basilica is classified as a baroque building. Two front towers (61 m) and a dome are the far visible characteristic attributes of this cross dome church. It is inclosed by a former Pauline Fathers (1708–86) and later Franciscan (1842–1996) monastery.
