Ravenna lies at the heart of mosaic culture, famous for its monuments of early Christian and Byzantine architecture certified by the UNESCO World Heritage List, as well as for its modern masters, restoration centers, schools and educational institutions. In 1924 a course of Mosaic was opened at the Academy of Fine Arts of Ravenna. Struggling to keep the striking legacy of the past the mosaic masters turned to using old mosaic techniques to implement new ideas. After the Second World War it was the beginning of a new era in mosaic art, when mosaic literally started speaking modern language. Since then, the notion of "mosaic" has acquired a new concept, now it means the art, which not only existed in the past but is alive and developing in the present. And in this new concept mosaic art is inextricably linked to Rovenna, the city that allowed the mosaic to continue in the future.
