The rather plain brick exterior of the octagonal Basilica di San Vitale belies the sumptuous 6th-century mosaics covering the apse and choir within, executed by unknown master craftsmen over many years and said one of the finest examples of Byzantine art in the world. Detailed Biblical scenes contrast with depictions of the Byzantine Emperor Justinian, surrounded by stylized floral motifs in green, red, and gold. A visit to the basilica to take in its extraordinary mosaics is a must during any visit to Ravenna; join a guided tour to best appreciate these uniquely important works of Byzantine art along with other top attractions like the Mausoleum of Galla Placidia, the Basilica di Sant'Apollinare Nuovo, and Dante’s Tomb. Ravenna is an easy day trip from Venice or Bologna, and can be combined with a stop in the nearby city of Ferrara.
