Cities That Were Built Without a Plan (And It Shows)

Cartagena expanded steadily within massive stone walls meant to hold off Caribbean pirates. Spanish colonial builders shaped the town around its curving coastline, defensive fortresses, and tropical heat. The streets do not follow a rigid grid; they bend toward shady plazas and glimpses of the sea. Along the narrow lanes, brightly colored houses have wooden balconies projecting overhead, protecting the pavement from the tropical sun.
