Ancient City Colonia Pietas Iulia Pola-Theater

After its conquest by the Romans in 177 BC, Pula became a Roman colony under the name Colonia Pietas Iulia Pola. During the reign of Emperor Augustus, in addition to the amphitheater, the Temple of Roma and Augustus, parts of the city wall with its gates, and the remains of two theaters were built. With the collapse of the Western Roman Empire in the 5th century, Pula fell under the rule of the Ostrogoths. In the 6th century, Emperor Justinian reconquered the city for the Eastern Roman Empire and developed it into a Byzantine naval base.
