Top things to do
The coquina walls and gun deck
The fort's signature shellstone walls and the upper gun deck, with cannons and harbor views over Matanzas Bay.
Weekend cannon firings
Costumed crews fire the historic weapons on scheduled weekends. Check the calendar, since it is the highlight when it runs.
Interior rooms and exhibits
The vaulted rooms around the central plaza, with exhibits on the fort's Spanish, British, and American history.
Make The coquina walls and gun deck the timed anchor
Put the timed or highest-demand stop first, then keep the rest of the day close and low-friction.
