The Church of Spirito Santo, also built by Theodoric and originally named Hagia Anastasis (Holy Resurrection). This was an Arian cathedral, and it was re-consecrated as the Catholic cathedral of Saint Teodoro (soldier and martyr of Amasea in Porto) in 526. Little remains of the original church after its reconstruction in 1543; some historians speculate that the original mosaics were already lost over a thousand years earlier during its Catholic reconstruction due to Arian themes. It is a typical three-aisled basilica.
