Tarragona

Tarragona seems to effortlessly juggle being both a UNESCO-listed tourist destination and a busy port with all the associated industry. Many ancient ruins remain from its time as the Roman colony of Tarraco. The Amfiteatre Romà is a 2nd-century arena facing the Mediterranean, the Necropolis contains Roman tombs, and traces of the Forum stand among the alleys of the walled, medieval Old Town. A walkway along the ramparts, the Passeig Arqueològic, has sweeping views of the city.
