Tarragona

In this effervescent port city, Roman history collides with beaches, bars and a food scene that perfumes the air with freshly grilled seafood. The biggest lure is the wealth of ruins in Spain’s second-most important Roman site, including a mosaic-packed museum and a seaside amphitheatre. A roll-call of fantastic places to eat gives you good reason to linger in the knot of lanes in the attractive medieval centre, flanked by a towering cathedral with Romanesque and Gothic flourishes.
