The oldest masonry fort in the continental United States
Castillo de San Marcos National Monument 1 S. Castillo Dr. (west lawn)
Come experience nearly 350 years of history at the oldest masonry fort in the continental United States. Built on land that was once home to the Timucua, the Castillo saw generations of soldiers from Spain, Great Britain, and the United States set down roots and protect the people of St. Augustine. Today, Castillo de San Marcos’ park rangers need your help in preserving this important place and its many stories for generations to come.
