Maker chciał ukształtować część Ziemi jako obraz Nieba. Tak narodziła się Istria i jak ogród pokryty cudownymi drzewami i szerokimi łąkami, przemyta głębokim błękitnym morzem, zachęca ludzi do szczęśliwego życia. Ale zazdrosny diabeł zniszczył jego pracę, rozdzierając worek, w którym anioł niósł niewykorzystane kamienie. Tysiące skał rozleciało się wokół ziemi Istrii, co uczyniło z niej ziemię kontrastów, delikatnych i szorstkich, żyznych i jałowych, słonecznych i chmurnych.  

The ground plan is elliptical, the longer axis measuring about 130 m and the shorter one about 100 m. Gladiator fights took place in the central flat area called the arena, while the spectators could sit on the stone tiers or stand in the gallery. It is believed that the Amphitheater 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, ... which can seat about 5,000 spectators. The underground passages, once used by the gladiators, nowadays host a regular exhibition of viticulture and olive growing in Istria in ancient times. The exhibits include reconstructions of machines once used for the production of olive oil and wine (mills, presses, vessels) and amphorae used for storing and transporting olive oil and wine. The Amphitheater is situated outside the old city walls because of its size and geographical configuration. The road that leads to the center was constructed during Emperor Vespasian, after whom it was named - Via Flavia. Even today it represents one of the main city roads.

The Forum was the nucleus of city life, its religious, administrative, legislative and commercial center. On the northern part of the Forum stood two twin temples and a central one dedicated to Jupiter, Juno and Minerva. Today only the Temple of Augustus has been fully preserved while of the second temple only the back wall, built into the Communal Palace in the 13th century, is visible. Ancient remains of the Forum have been found during the construction of new buildings, the latest ones being "Agrippina and her time" (1st century AD). The remains have been partly restored and are now exhibited in the bank built on the site. Even today the Forum is the administrative and legislative center of the city. During the summer months it is the venue for numerous cultural events.

The gate and wall were pulled down in the beginning of the 19th century as a result of the city expansion outside the city walls. The Arch was constructed in Corinthian style with strong Hellenistic and Asia Minor influences both in the method and ornaments. As the eastern side was not visible it has remained for the most part uncarved, while the western, town side is richly decorated. Today numerous cultural performances, theatrical and musical, are held on the square next to the Arch. The adjacent street is a shopping area.
