The Mausoleum of Galla Placidia is one of the eight structures in Ravenna inscribed on the World Heritage List in 1996.
As it was built in 425-430, it’s the earliest mosaic monument.
Its cupola is completely covered with mosaics, representing 8 apostles. Over the door, you can see Jesus as the Good Shepherd, young, beardless, with flowing hair, surrounded by sheep. Inside, there are 3 sarcophagi, the largest falsely believed to house the mortal remains of Galla Placidia, the daughter of Emperor Theodosius, her brother, Emperor Honorius, who had moved the capital of the Western Empire from Milan to Ravenna, and her husband, Emperor Constantius III. In fact this building was the oratory of a wider church the Holy Cross.
