The ceremonial gateway arch that frames the approach to Ernesto Cortissoz International Airport, designed as a statement of civic ambition. Barranquilla has long styled itself as the "Puerta de Oro" — the Golden Gate — of Colombia, a title reflecting its historical role as the country's main entry point for trade and immigration. The arch is a modern piece of public architecture, best seen on arrival or departure, though it's also accessible from the Vía 40 if you want a closer look.
