¤ Fort San Carlos (2) (State Historic Site)
(1816 - 1821), Old Fernandina
A Spanish 10-gun earthwork fort with trace remains located at the foot of Estrada Street. It replaced an earlier Spanish water battery that had been captured by American and British settlers during the "Patriots' War" of 1812 to establish the "Republic of East Florida". The United States Army took control from the Patriots after only one day. The Spanish regained the town in 1813. A private army led by Sir Gregor MacGregor seized the new fort in 1817, and successfully defended against the Spanish forces during the "Battle of Amelia Island". The Spanish had erected a four-gun battery nearby on McClure's Hill to bombard the fort. Shortly after the battle, pirate Luis Aury briefly took control of the fort. American troops occupied the fort to drive out the privateers in late 1817, and abandoned the fort shortly after the cession of Florida in 1821.

Castillo de San Marcos (National Monument)
(1672 - 1900), St. Augustine *PHOTOS*
St. Augustine was the first permanent white settlement in the United States. This is the site of nine earlier wooden forts, all Spanish, dating back to 1565. The site of the original 1565 work has been recently excavated, just north of the castle. The second and third sites in 1566 were on Anastasia Island. The fourth site was near the Old City in 1572. The fifth fort (near the Old City) in 1578 was destroyed by Sir Francis Drake in 1586. The sixth fort (wooden) in 1568 was named Fort San Juan de Pinos (Pinillo), and was closer to the original site. The seventh (1586), eighth (1604), and ninth (1653) sites were close to the present fort. English pirates sacked the ninth fort in 1665. Rebuilt in 1666, it was then destroyed by the English in 1668.

The present structure, Castillo de San Marcos (also called El Presidio de San Augustin), was built with coquina (shells and stone) beginning in 1670, and is the oldest masonry fort in the U.S. The fort was rebuilt or reconfigured in 1738, 1752, and 1762. The seawall was built in 1696. The Hornwork was built in 1706, rebuilt or modified in 1746 and 1776. The Tenaille was built in 1791. The Cubo was built in 1704, rebuilt or modified in 1718, 1738, 1775, 1797, 1808, and 1819. The Rosario was built in 1718 as an earthwork, rebuilt or modified in 1720 (portion in stone), 1740, 1761 (all stone), and 1776. A watchtower was built at the inlet in 1738, rebuilt in 1770 and 1824. An outer battery was built at the inlet in 1740. The fort was held from 1765 - 1783 by the British and called Fort St. Mark. (Note: Not to be confused with the American Fort St. Marks (1818 - 1824) in St. Marks.) The British made improvements to several of the outworks in 1775 and 1776 (Fort Moultrie (1) on the Cubo), with two outer redoubts in 1776 to the south, and built four additional outer redoubts in 1781 to the south of the fort. The Spanish rebuilt two of the redoubts in 1797 and 1806. The Americans occupied the fort from 1821 - 1900, with the Confederates briefly holding it in 1861 - 1862. The fort was known as Fort Marion from 1825 until 1942, when the original Spanish name was restored. It was used as a prison for Seminole Indians in 1836, and again from 1886 - 1894 for Apache Indians. One 8-inch rifled Rodman was emplaced here in 1897 for target practice. It was dismounted in 1898. A temporary sand-covered timber reveted battery with two sand-covered timber magazines was built in 1898 - 1899. The Castillo was declared a National Monument in 1924. Admission fee.
