Maritime-Related National Parks in Puerto Rico
- Puerto Rico?s geographic position at the western edge of the Caribbean made San Juan one of the key frontier outposts of Spain?s West Indies dominions. San Juan National Historic Site includes Castillo San Cristóbal, Castillo San Felipe del Morro, Fortín San Juan de la Cruz (known locally as El Cañuelo), and three-fourths of the city walls.
