Specificità, interdisciplinarità e co-responsabilità. Il caso del cantiere didattico di restauro della decorazione pittorica all’intradosso della volta a incannucciato del coro della chiesa dell’Immacolata di Orsola Benincasa

The need for a close collaboration between architectural conservators and conservators of decorated architectural surfaces, through a commitment of co-responsibility in the project, is well testified by the recent conservation activities and a future didactic worksite for the UniSOB Master’s Degree Course in Conservation and Restoration, on the 18th century pictorial decoration of the wooden vault that covers the choir in of the church of Immacolata Antica, within the monastic citadel of Orsola Benincasa. The paper presents the first results of an ongoing interdisciplinary didactic and research activities that have involved experts from the various disciplines related to Conservation, from Diagnostics to Surveying and Construction History. Through the interweaving of data from the historical investigation, the geometric survey, the interpretation of constructive features and the experience of the conservation worksite, attention is drawn to the current problems of preservation of the wooden vaulting, both on intrados and on extrados, considered in its multiple aspects connected to the pictorial decoration and the structure.
