The thick walls of the Fort San Cristobal in San Juan, Puerto Rico protected this former Spanish settlement for centuries from foreign invaders. This once military complex is now a museum under the United States National Park Services and is one of the most visited heritage sites in Old San Juan. Last February, the Eastern Caribbean cruise I was on made a brief stop at this US territory giving me ample time to explore the neighborhood close to the port. The fort was conveniently located a few minutes from the ship so I braved through the humidity and found myself standing in front of this behemoth of a wall. At the gate, I noticed the golden light of the setting sun casting geometric shadows while making the walls glow creating an interesting photo opportunity for me. The rich blue cloudless sky also made the golden yellow walls of the fort pop out in this photograph. Unfortunately, my cruise only stopped for a few hours so I never really got to explore much of Old San Juan. I hope to visit again someday and maybe include a visit of the El Morro for more photo opportunities.
