GAINESVILLE, Fla. (AP) — What do St. Augustine’s Castillo de San Marcos and Egmont Key near Tampa have in common? They are two of thousands of Florida’s heritage sites that are vulnerable to rising seas. “Jupiter Lighthouse, Fort Zachary Taylor in Key West, Fort Jefferson and Fort Pickens in Pensacola — all of these places are threatened,” said Clay Henderson, executive director of Stetson University’s Institute for Water and Environmental Resilience.
The Castillo de San Marcos withstood two sieges in 330 years and changed hands five times, but its latest invader — the rising Atlantic Ocean — threatens to erode the historic St. Augustine fortress.
