¤ Charles Fort

A small earth and log fort built by 150 French Huguenots under Jean Ribault, and abandoned soon after the failure of the colony. A monument was erected in 1926 on the supposed site, which is now known to be the site of Spanish Fort San Marcos (a). The Spanish Fort San Felipe (a) was built over the actual ruins of Charles Fort (see below). This site was excavated in 1997.
¤ Santa Elena Forts 
(1566 - 1587), Parris Island
The Spanish under Pedro Menéndez de Avilés built the settlement of Santa Elena over the ruins of the French Charlesfort settlement. The first fort built here was named Fort San Salvador (1566). Fort San Felipe (a) (aka Fort San Sebastian) (1566 - 1570) was a larger work, built over the actual ruins of Charles Fort. Its site was excavated in 1997. After its powder magazine exploded, it was rebuilt in 1570 on higher ground (Fort San Felipe (b)), rectangular with two earthen and timber bastion, and moated with an outer stockade. Indians destroyed the settlement and the fort in 1576. This second site was first excavated in 1979. In 1577 the Spanish rebuilt the town and built a new triangular fort, called Fort San Marcos (a) (1577 - 1583), 200 yards south of Fort San Felipe (b). It was rebuilt in 1583 (Fort San Marcos (b)), probably on the site of Fort San Felipe (b), and destroyed when the Spanish abandoned the area in 1587 and returned to Florida. The coastal region encompasing the area between the Savannah River and the Edisto River was known to the Spanish as the Orista Province. The Charles Fort Monument (1926) is located at the site of Fort San Marcos (a), which was first excavated in 1979, and again in 1998, underneath the Parris Island golf course.
