The Castillo de San Marcos in St. Augustine is a winner in so many categories — it has fascinating, history, it offers spectacular views and when the rangers fire the cannons (on weekends), it’s dramatic and entertaining.

It is the oldest masonry fort in the United States, built from 1672 to 1695, a hundred years after St. Augustine was founded by the Spanish.

It’s located right next to the walkable Old Town area and it has adjacent parking.
