Galla Placidia (386-452), sister of Honorius, the Roman emperor who in 402 moved the capital of the Western Empire from Milan to Ravenna built around 425-450 this small mausoleum shaped like a Latin cross and famous for the splendor of mosaics. Less likely was the mausoleum of Galla Placidia her tomb as sources report that she died and was buried in Rome (450) where her remains still lie in the chapel of Santa Petronilla. The exterior is very simple, in contrast with the richness of interior decoration. The atmosphere of the Mausoleum of Galla Placidia is definitely magic. Entering the small building visitors are struck by the sudden transition from daylight to the reproduction of the atmosphere at night. The innumerable stars in the dome have struck the imagination and the sensibilities of visitors to Ravenna. The plan of the small building is a Latin cross. Outside has a simple brick hanging in the central part, with a square base, the higher and lower arms with a gabled roof; the only decoration allowed outside is formed by the arches. This choice is due to the meaning of inner beauty preached the Gospel (overcome the barriers of appearance that deceives). The interior, however, is magnificently decorated by a series of mosaics that although periodically restored still appears intact. Since Galla Placidia frequently stayed in Constantinople, one could argue that the artist responsible for these were Byzantin. Perhaps it is more correct to think of a participation of workers of different nationalities, because the volume of naturalistic figures of St. Lawrence and the Good Shepherd, pictured above the entrance to the shrine area strongly elevates the Roman West as independent and not as one area of the Byzantine Eastern Empire.  At the end of the arms are three sarcophagi. The central dome dominates the interior.
