Castillo de San Marcos - St. Augustine, Florida

Kicking off our exploration is the Castillo de San Marcos, the oldest masonry fort in the continental United States. Built by the Spanish in the late 17th century, this formidable structure sits on the waterfront of St. Augustine, Florida. Its coquina stone walls, made from compressed shells, have withstood centuries of storms and sieges. Visitors can explore its imposing ramparts, watch historic reenactments, and learn about its role in protecting Spanish Florida from British invaders. The hauntingly beautiful sunsets over the fortress make it a perfect spot for both history buffs and romantic souls.
