Old San Juan - San Juan Gate Puerta de San Juan

Built in the late 1700s, the San Juan Gate (Puerta de San Juan) is one of six original massive wooden doors in the City Wall surrounding Old San Juan. Each night, the doors were closed at sundown to protect San Juan's inhabitants and impede access to the city.

The Puerta de San Juan is actually a tunnel through the thick city walls and in the days of yore, all goods from trading ships had to pass through it. The San Juan Gate is one of three remaining gates in the city and from the Puerta de San Juan visitors can wander out onto Paseo de la Princesa.
