Step through the open door and into the darkness of the tunnels of Castillo San Cristobal. I was so sure that I had posted this door already. After searching for it, it seems I have left it out of my posts from San Juan, Puerto Rico.

This is the first door, leading to all the others as featured on “Deep into a Tunnel.”
