Arian Baptistery

The Arian Baptistry in Ravenna, Italy is a Christian baptismal building that was erected by the Ostrogothic King Theodoric the Great between the end of the 5th century and the beginning of the 6th century A.D., at the same time as the Basilica of Sant' Apollinare Nuovo.

Theodoric was an Arian Christian and decided to let the Goths and the Orthodox Chalcedonian Christians live together but separately, and so there were separate neighborhoods and separate religious buildings.

Near his palace, the king commissioned an Arian cathedral, now called the Church of Spirito Santo, but originally named Hagia Anastasis. It was re-consecrated as the Chalcedonian cathedral of Saint Teodoro in 526 AD.
