Castillo de San Marcos
Spain began raising the Castillo de San Marcos in 1672, carving its walls from coquina, a soft local shellstone that absorbed cannonballs rather than shattering, and the fortress never once fell to assault. Over two centuries it changed flags repeatedly and, under United States control, became a prison where Seminole leader Osceola was held and hundreds of Apache captives were confined, many of whom died behind its walls. Visitors and night watchmen have long reported the shapes of Spanish soldiers pacing the ramparts as though still on duty, an unexplained light moving in the old watchtower, and sudden cold spots in the lower storerooms and cells. The most repeated legend tells of soldiers sealed away in a hidden chamber, their phantom footsteps said to march through the stone corridors before dawn. Whether echo or imagination, the fort wears its long memory of confinement quietly into the dark.
