The mosaic decoration reflects the Beuron style, thus corresponding to the murals in the church interior. The mosaic's unsatisfactory condition gave rise to the primary inspection. The mosaic decoration showed damage in the form of open defects that uncovered the bedding mortar after mosaic tesserae fell off, and also a big amount of cavities. At first, the initial restoration, art history, and natural history research was carried out; the results were expanded during the restoration. Based on the research, a proposal of restoration treatment was drawn up. Subsequently, essential restoration was carried out to preserve the mosaic. ER
