Florida's Oldest Fort Battles Rising Tides
6 Jul
Summary
- Seawall improvements began Monday at Castillo de San Marcos National Monument.
- The project aims to protect the historic fort from storm damage and rising waters.
- Construction is expected to take 18 months, concluding around January 2028.

The National Park Service has initiated critical seawall improvements at the Castillo de San Marcos National Monument, with work beginning Monday. This endeavor, planned for over two years, is designed to safeguard Florida's oldest city and its historic fort from increasing storm damage and water threats.
The project involves constructing new, raised seawalls to the north and south of the fort. The primary seawall, located directly east of the Castillo, will undergo significant historic preservation treatments to retain its original character and charm.
Engineers, architects, and resource specialists collaborated on the undertaking, incorporating public feedback. Despite some temporary closures of specific grounds for safety, access to the fort itself will be maintained throughout the construction.
This extensive project is projected to last 18 months, with an anticipated completion date around January 2028. The initiative mirrors ongoing efforts to protect St. Augustine's downtown area from King Tides and enhance pedestrian safety.
