I participated in a digital marketing summit this past week organized by Yodle, a prominent local internet marketing company. Not especially worthy of note. But they chose to hold it in San Juan, Puerto Rico. That meant a chance to tack on some time after the sessions were over and get out to shoot some pictures. First stop: the 16th-century Spanish citadel known as Castillo San Felipe del Morro.
nautilus-like underside of a spiral staircase placed to give soldiers quick access between levels of the fortress.
Spent a wonderful couple of hours wandering around this impressive fortress, and gained a firsthand appreciation of Spain's military prowess during the colonization of the New World.
