The Basilica of Sant'Apollinare Nuovo has only gained its current name recently, when the relics of Saint Apollinaris were transferred from the neighboring Basilica in Classe. Its history, however, is much longer. First consecrated in the early 6th century by King Theodoric of the Ostrogoths as an Arian church, the building has seen many renovations both in structure and decoration while maintaining its unique style — an elegant mixture of western and eastern art — and its amazing Byzantine mosaics.
