The restored Colonial architecture in the center of Cartagena, Colombia, a UNESCO World Heritage site since 1984, is so gorgeous that the overall effect can be overwhelming. So much stone! So much color! So many balconies! When we traveled to Cartagena we particularly loved the mystery and history of the doors and windows of Cartagena, as you can see in this photo essay. Often shut to keep the Caribbean sun at bay, we couldn’t help but wonder what we’d see if we could just peek inside.
