Cartagena’s Old Town (Colombia). 'The hands of the clock of the Puerta del Reloj wind back 400 years in an instant as visitors enter Cartagena’s walled old town. Strolling the streets here is to step into the pages of a novel by Gabriel García Márquez. The pastel-toned balconies overflow with bougainvillea and the streets are abuzz with food stalls around magnificent, Spanish-built churches, squares and historic sites.' http://www.lonelyplanet.com/colombia/caribbean-coast/cartagena
