One of Ravenna's biggest attractions for day visitors and people on beach excursions from Venice is the Mausoleum of Galla Placidia, which houses the oldest Christian mosaics in the city. Mosaics in Galla Placidia's mausoleum, which is located behind the Basilica di San Vitale, are among of Ravenna's oldest and most magnificent.
Roman Empress Galla Placidia is thought to have commissioned the early fifth-century Christian chapel in Ravenna, Italy, known as the Mausoleum of Galla Placidia, which, until recently, was assumed to contain her grave. The powerful Galla Placidia, the daughter of Roman emperor Theodosius I, constructed the Mausoleum of Galla Placidia (386-452) as a burial structure (Galla Placidia's brother Honorius was the one who moved the capital of the Western Roman Empire to Ravenna).
