(The Castillo de San Marcos) in St Augustine, Florida


A monument not only of stone and mortar but of human determination and endurance, the Castillo de San Marcos symbolizes the clash between cultures which ultimately resulted in our uniquely unified nation. Still resonant with the struggles of an earlier time, these original walls provide tangible evidence of America’s grim but remarkable history.

The Castillo De San Marcos was the tenth in a series of forts to protect St. Augustine. The previous nine were constructed of wood. The work on Castillo began 1672 in the month of October.  A pirate attack in 1668 and the founding of Charleston by the English in 1670 prompted the Queen Regent Mariana of Spain to approve the building of a powerful masonry fortification to defend Florida. The Castillo is the largest fort ever constructed by Spain in North America.  Constructed using coquina rock quarried across the bay on Anastasia island, it took 23 years to complete.

James Moore of South Carolina tried to capture St. Augustine. Queen Anne’s War was then underway and Moore came south to lay siege to the Oldest

The 1,500 soldiers and citizens of St. Augustine took shelter within the fort and held off the English army for 52 days until they were relieved by a Spanish fleet from Cuba. Moore burned the city but became the first of many commanders that tried and failed to take the Castillo. 312606_315281931818495_1383588428_n_zpsudydeqle

In 1763, as an outcome of the Seven Years’ (French and Indian) War, Spain ceded Florida to Great Britain in return for La Habana, Cuba. The British garrisoned Matanzas and strengthened the Castillo, holding the two forts through the American Revolution. The Treaty of Paris of 1783, which ended the war, returned Florida to Spain.

The Americans renamed the Castillo Fort Marion and used it to house Indian prisoners during the Seminole War 1835-42. Confederate troops occupied it briefly during the Civil War and Indians captured in western military campaigns were held there later on. It was last used during the Spanish-American War as a Military Prison.321644_315264338486921_1164742333_n_zps5hknh0ui
