This study aims to highlight the specific manifestations and iconography of the Eucharistic devotion of the Rosalienkapelle of the Jesuit Church Kirche am Hof, Vienna. By consulting the Litterae Annuae (the annual report of the
Austrian Province to the General of the Jesuit Order in Rome) and the Historia Domus of Kirche am Hof, I was able to emphasize new aspects of the decoration, such as stuccowork, altarpieces, and ephemeral decorations. Dynastic
representation and international alliances of the Habsburgs played an important part in shaping the architecture and decoration of the church dedicated to the Nine Choirs of Angels. The statue of the Virgin Mary standing in front of the church was inspired by the monument of the Immaculate Conception in Munich that was governed by the Wittelsbachs, who were strong allies of the Habsburgs. Masters executing stuccowork in Munich and Vienna came from the Lugano region of Northern Italy. Netherlandish influences can also be detected in the decoration of the Rosalienkapelle, embellished with wall paintings inspired by Peter Paul Rubens’ designs.
