The most famous and important monument, the starting and ending point of every sightseeing tour is the Amphitheatre, popularly called the Arena of Pula, which was once the site of gladiator fights. It was built in the 1st century AD during the reign of Emperor Vespasian, at the same time as the magnificent Colosseum in Rome.

It is believed that the Amphitheatre could seat about 20,000 spectators. Local limestone was used for its construction. In the Middle Ages it was the site of knights tournaments and fairs. Today it is the venue for summer performances - the Film Festival, Opera Season, Equestrian Festival, concerts, and can seat about 5,000 spectators.

Belvedere in Novigrad is the only loggia in Istria that is situated by the sea. It probably rests on an older part of the defensive walls (ruins of a tower). Presumably constructed in the 16th century, the Loggia was renewed in the years 1860 and 1930.
