Celebrated architect Gaudí left his imprint on Barcelona in more ways than one. His unique incorporation of color and organic form into the city’s architecture sought to infuse the urban landscape with nature’s harmony. In step with Gaudí’s vision, Barcelona’s modern-day city planners have placed Spain’s second-largest city at pole position for “Smart City” planning. Its planners envisage a harmonious living space where buildings generate their own energy needs; transport systems, street lighting and electric vehicle charging networks are powered on renewable energy; an abundance of rooftop gardens and green spaces create carbon sinks; and where its community can connect via state-of-the art information networks across the city. It may not be there yet, but Barcelona is no less an inspiring city to live in today than it will be tomorrow. Its ocean playground, dazzling architecture, heady nightlife, its plethora of open air spaces and activities for all ages, dazzling architecture, street markets and colmados (old-style grocer’s shops), its rich cultural heritage and its passion for the arts and sports (not least, football!) make it easy to understand why so many foreigners—which account for roughly 7% of residents—choose Barcelona to live and work.
