Abstract
The article analyzes the sources on the history of Saints Peter and Paul Garrison Church (the former Jesuit Church) discovered in the funds of Vasyl Stefanyk National Scientific Library of Ukraine in Lviv. In particular, the documents that are of practical importance for the process of church revitalization as the building remained closed from 1946 until 2011 are distinguished. The significant corpus of sources concerning the church history is the archive of Vasyl Stefanyk National Scientific Library of Ukraine in Lviv, the depository of which was located in the church until the end of 2011. With these documents, it is possible to trace the history of the church building during the Soviet time and the changes that happened during this period. Moreover, the collection of photographic materials with the depiction of different parts of the church constitutes a significant corpus of sources. This information is valuable for the conservation professionals working on the renewal of church exteriors and interiors. Particularly, the photographs that show the process of the roof restoration in 1959 offer an opportunity to assess the degree of the ceiling destruction during the Second World War. Photographs of the frescoes in the main nave demonstrate the state of the ceiling and frescos as of the beginning of the 20th century and therefore give an insight into the progress of conservation works during the interwar period. The analysis of the photograph of the altar of Saint Stanislaw Kostka makes it possible to understand what one of the three chapels in the church looked like. The other two chapels (of the Virgin Mary and Saint Stanislaw Kostka) will be restored in course of time. As for the third chapel of Saint Benedict the Martyr, important documents concerning the restoration of this chapel at the beginning of the 20th century are stored in the funds of the library. With these documents, it is possible to specify the appearance of the chapel and the peculiarities of its decorations, as the chapel does not belong to the church nowadays. To sum up, it can be stated that the funds of Vasyl Stefanyk National Scientific Library of Ukraine in Lviv contain a relatively small amount of materials on the history of Saints Peter and Paul Garrison Church (the Jesuit Church). At the same time, some of them are important for the studies of the history of the church, so they deserve attention from the researchers.
