It can be reached from the Augustus Arch by following Via Bastioni Orientali, where the Medieval-Malatesta city walls immediately come into view, until the intersection with Via Roma. Together with the Arch and Tiberius Bridge, the Amphitheatre is the third of the city's main Roman monuments. It was built in the second century A.D. under Emperor Hadrian.
The brick structure is elliptical in shape with an arena measuring 76.40 by 47.40 metres, similar to the Coliseum's size. The number of audience members it could accomodate was probably around 10 or 12 thousand, not counting those who could be seated on the wooden balconies that were part of the original structure. The Amphitheatre in Rimini is one of the most imposing in the region, as well as being the only one partially surviving in Emilia-Romagna (few traces remain of the one in Imola).

Nawadays, it is possible to visit the ruins on request by contacting the City Museum, which organizes guided tours for schools and tourist groups. Some remains are on show in the archaeological section of the Museum.
