VILENICA BenediktaThe Church of the Blessed Virgin Mary makes part of the Franciscan Monastery at Jastrebarsko. Parts of the Monastery date back to the 16th century. The medallion in question takes the central part of the ceiling, above the chancel. It was painted on top of several older paint layers, in 1908, as a part of the overall church decoration by the Austrian - Italian painter O. Bierti.

In 2012, the medallion was detached from the ceiling, using the stacco method, as the ceiling needed structural repairs. It was taken to the Academy of Fine Arts of Zagreb, The Department of Conservation and Restoration of Art. It was detached in in five sections. One of them was restored and conserved by D. Marijić, as part of the final year project, in 2016. Two of the remaining four sections are currently being restored by the author of the presentation as part of her final year project. The aim of this exercise is to prepare them for their reintegration in situ, as the sections are going to be put back in their place in the church in which the rest of the painted decorations have already been restored.

This presentation deals with the issues of detachment of wall paintings (particularly of those done on curved surfaces) and the making of new supports. It also gives suggestions for the display of the medallion.
