One of the largest surviving ancient Roman arenas. The works started during the reign of Augustus, but the construction was replaced by another one made during the reign of Claudius. It is believed that Pula Arena was created between 27 BC and 68 AD. Later, due to the order by Vespasian in 79 AD, it was enlarged and became an arena of gladiator fights. The works were completed two years later. During five centuries, Pula Arena was a witness of thousands of deaths. In the Middle Ages, it was a place of medieval fairs and occasional knight tournaments. It was a source of stone for many building including the Pula Cathedral. Finally, in the early 19th century the first restoration works started. Since 1932 it has been used for public meetings and theater productions.
