Designed to accommodate 23,000 spectators, Pula's arena is the sixth-largest building of its type in the world (after the Colosseum in Rome and similar arenas in Verona, Catania, Capua, and Arles). Construction was completed in the 1st century AD under the reign of Emperor Vespasian, and the Romans staged gladiator games here until such bloodthirsty sports were forbidden during the 5th century. During the 16th century, the Venetians planned to move the Arena stone by stone to Venice, where it was to be reconstructed in its original form. The plan failed, and it has remained more or less intact, except for the original tiers of stone seats and numerous columns that were hauled away for other buildings. Today it is used for summer concerts (by musicians including Sting, James Brown, and Jose Carreras), opera performances, and the annual film festival in late July. The underground halls house a museum with large wooden oil presses and amphorae.
