The Castillo de San Marcos National Monument is a historic fort located in St. Augustine, Florida.

It was built in the 16th century by the Spanish and served as a defense structure against pirate attacks and British invasions.

The British later took over the fort during the Seven Years’ War and remains one of the best-preserved examples of Spanish colonial architecture in the United States.

The monument is now under the care of the National Park Service and attracts visitors from around the world.

In this article, I will take you through the history of Castillo de San Marcos, how and when to visit, and finally, I’ll give you tips on how to make the best of your tour to this national monument.

Let’s first find out the history behind it:

The History of Castillo de San Marcos

A whole view of Castillo de San Marcos National Monument

St. Augustine was founded in 1565 by Spanish Admiral Pedro Menéndez de Avilés, but the first 100 years were marred by pirate attacks and poverty.

During that period, nine wooden forts were built and destroyed by rot, termites, storms, tides, and fires.

In 1668, English pirate Robert Searle attacked St. Augustine, killing 60 people, looting, and ransoming 70 others. This raid convinced the Spanish crown of the need for a stronger fortification.

It was not until 1672 that Governor Manuel de Cendoya and engineer Ignacio Daza began the construction of the Castillo de San Marcos. Made from coquina, a local limestone, the fort’s construction faced numerous challenges including financial setbacks, epidemics, and changing plans.

The fort was completed after 23 years of construction under six different governors (1695). The project cost approximately 138,375 pesos, much higher than the originally planned 70,000 pesos.

Labor Force

Local Native American tribes, including the Guale, Timucua, and Apalache, were the primary labor force. Despite being paid and fed, many faced mistreatment and harsh working conditions.

The labor took a toll on the Native American population, leading to disease and cultural assimilation, contributing to the foundation of the Seminole tribe.

Free and enslaved Africans also worked on the Castillo. The Spanish system allowed for self-purchase or service to the crown for freedom, creating a class of free blacks in St. Augustine.

The fort became a refuge for enslaved people escaping from the English colonies, offering freedom through service to the Spanish crown.

The construction workforce also included professional artisans from Cuba, Spain, and the Carolinas, English prisoners, and local Spanish peons. Convicts and soldiers also contributed to the construction.

Colonial Conflicts

In 1702, the fort withstood a siege by British forces from South Carolina during Queen Anne’s War. And between 1739 to 1748, during the War of Jenkins’ Ear, the British again laid siege but failed to capture the fort.

Florida was ceded to Britain following the Treaty of Paris in 1763. The fort was renamed Fort St. Mark.

20 years later, after the American Revolutionary War, Florida was returned to Spain and the fort’s name reverted to Castillo de San Marcos.

In 1821, Florida was ceded to the United States and was renamed Fort Marion.

During the American Civil War (1861-1865), the fort was held by Confederate forces until 1862 when it was recaptured by Union troops.

The fort was used to imprison Apache leader Geronimo and other Apache families in 1886. The fort was later decommissioned as a military post in 1900.

In 1924 Fort Marion was designated a National Monument and in 1933, the fort was handed over from the War Department to the National Park Service.

Then, in 1942, Congress approved renaming it Castillo de San Marcos to honor its Spanish heritage.

Let us now look at the significance of this fort and what makes it important…
