Forts El Morro and San Cristóbal along with 2.5 miles of city wall complete a fortification system that protected Puerto Rico, San Juan harbor and much of Spain’s interests in the “New World” from pirates and foreign invasion. Spain spent over 250 years building and fortifying this system considered “state of the art” for its time. Builders used the best engineering and architectural technology available at the time. Through this defense system, Spain controlled all access to the Caribbean Mexico and South America. San Juan harbor was the first major port ships would pass which could provide supplies such as water, food, etc.  Ships would stop here for provisions before continuing on to Mexico or South America.
