On a ship's excursion, we visited the octagonal Basilica di San Vitale, completed in 547 and renowned for its fine Byzantine mosaics, and continued to the Tomb of Galla Placidia, a jewel in 10-29-2012, Ravenna's crown. At Dante's Tomb, we learned the history of Italy's greatest poet and at Sant'Apollinare Nuovo, we walked in the 6th century footsteps of the Ostrogoth King Theodoric. We returned to the pier using the ship's shuttle service.
