Using this Handbook
Castillo de San Marcos National Monument is located in the longest continuously inhabited community founded by Europeans in the United States. This handbook tells the intercultural story of the long effort to build the Castillo and the emergence of a new Nation. The Guide and Adviser provides a brief guide to Saint Augustine and other related National Park Service areas in Florida.
From the air the rationale for the layout of Castillo de San Marcos is readily apparent: no wall or approach is unguarded.
