Byzantine culture is one of the milestones of European cultural heritage. For centuries, it spread all over the Mediterranean a homogeneous civilization despite regional diversities with strong influence over later European artistic and cultural expressions. Nevertheless, nowadays the wide heritage of the Byzantine art in Europe is undervalued, even if each Mediterranean region preserves remarkable memories and traces of its Byzantine past. The BYZART project proposes to raise awareness about this impressive heritage, by showcasing collections of archive photographs, audio-visual materials and 3D reconstructions in Europeana Collections. We aspire to utilise and building upon existing Byzantine content already in Europeana.
