Ravenna, the city of mosaics, the city of art and culture, is an ancient city that 1600 years ago became the capital three times; of the western Roman empire, of Theodoric King of the Goths and of the Byzantine empire in Europe.
The magnificence of this period has left Ravenna with a great heritage of historical buildings. There are no less than eight buildings declared World Heritage by UNESCO.
The art of mosaics did not originate in Ravenna but its greatest expression is to be found here. It was here that Christian iconology originated, a mixture of symbolism and realism, of Roman and Byzantine influence.
