When I walk around a city I am always fascinated by the doors I see. To me doors are more than just entrances and exits. They represent the spirit of the house. Doors tell you if they home is rich or poor. They can tell you if the owner is attentive to detail. Doors are also secret keepers. Nobody knows what is behind them, but they invite you to try and enter to find out what is happening. Here are some of the doors I found walking around Old San Juan.
