Among the places of historical, artistic and cultural interest, which a passing tourist should absolutely not miss, there is first of all the vast archaeological area of Forum Traiani, the important defensive center of the imperial era famous for being the main outpost Roman of all O internal Sardinia. It is certainly worth a thorough visit above all for two reasons: firstly because the structures and architecture are unusually well preserved than usual; secondly because inside the archaeological area it is still possible to observe today how the Romans did the baths, thanks to the survival of all the main buildings that made up the experience of the salus per aquam: thus we observe environments related to the calidarium, the frigidarium, the tepidarium and the laconicum, but above all the suggestive swimming pool, still filled with thermal water, dedicated at the time to the natatio.
