Why go
The shore-side visit introduces the landscape around the historic fort. Reaching the fort island is an additional ferry activity, so decide whether your plan is for the mainland or both parts. Separating the shore landscape from the island visit helps make the monument’s setting understandable, while allowing a useful mainland stop when a crossing does not fit your plan.

The full story
In 1740, James Oglethorpe's forces used Matanzas Inlet during their blockade of St. Augustine. The city survived the siege, but the episode showed that Castillo de San Marcos could not secure every approach. Spain began a separate defensive tower that year and completed it in 1742. Engineer Pedro Ruiz de Olano designed the fort on present-day Rattlesnake Island. Convicts, enslaved people and troops from Cuba provided the labor. Pine pilings supported the structure in marshy ground, while locally available coquina formed its masonry walls. A small rotating garrison from St. Augustine watched an inlet within cannon range. The name Matanzas recalls an earlier episode: Spanish forces executed French Huguenots associated with Fort Caroline here in 1565. Understanding that history places the tower within a longer struggle over the coast. Restoration in the twentieth century stabilized the deteriorating building, preserving evidence of Spain's response to this vulnerable waterway.
Useful to know
- Collect a boarding pass at the Fort Matanzas Visitor Center if you intend to take the ferry.
