This octagonal temple of the sixth century is a true hymn to life, starting from its dedication to the Holy martyr Vitale. Its dome, object of study of the greatest architects of the world, from Brunelleschi to Palladio, from Antonio da Sangallo the Younger to Le Corbusier, makes pendant with the perhaps most famous mosaics of the city: those that represent the emperor Justinian and his wife Teodora, muse of many more or less contemporary artists, from Gustave Klimt to Karl Lagerfeld, from Christian Lacroix to many other masters of style and refinement.
