Most of the preserved Roman monuments are found in Pula. The Temple of Augustus dedicated to goddess Roma and Emperor Augustus was built between 2 BC and AD 14. It stood in the Roman Forum, also the name of the present day square, where a small collection of Roman sculpture made of stone and bronze is now displayed.

Hercules’ Gate was incorporated into the ancient city walls, probably the first monument that the Romans erected after coming to Pula, as well as the Twin Gates named for the two arches and built between the 2nd and 3rd centuries. The Triumphal Arch of the Sergi, drawn even by Michelangelo when he visited Pula in the 16th century was built in Corinthian order about 30 BC. Particularly interesting is the Small Roman Theatre within the city walls, as distinguished from the large one which stood outside the city walls, but has not been preserved.

The magnificent Amphitheatre, used primarily for gladiator fights, was built during the Emperor Vespasian rule in the 1st century. It was constructed in the form of an ellipse and could embrace about 20,000 spectators. The underground rooms of the Amphitheatre house the permanent exhibition 'Olive and Wine Growing of Istria in the Classical Antiquity' with reconstructions of machines for producing olive oil and wine (mills, presses and vessels) as well as numerous amphorae used for oil and wine transportation.
