Barcelona, Catalonia's dynamic capital, is a gorgeous seaside city known for its alluring cultural attractions, legendary architecture, world-class dining scene, and Mediterranean sunny lifestyle. Where colossal temple columns, historic city walls, and subterranean stone passages provide a peek into Roman-era Barcino, the Gothic quarter's gloomy streets, past peaceful plazas, and majestic 14th-century cathedrals transport you to the Middle Ages, and the mix of inventive and quirky wonders of Modernisme, by Gaudi and his Catalan architectural colleagues mesmerize you. Where a jog, a bike ride, or a long leisurely stroll along the seaside, followed by a refreshing dip, against a backdrop of sun-drenched beaches makes your day complete. Where flamenco's rapid-fire rhythms, brassy jazz spilling out of cellars, and hands-in-the-air indie-rock at old concert halls make your night.
