Description of Castillo de San Marcos

Castillo de San Marcos or Castle of Saint Mark is situated at 11 South Castillo Dr, St. Augustine, Florida in United States. The city of San Agustín was founded by Spain in 1565. During its first century of existence, nine wooden forts defended the position. After the attack of the English pirate Robert Searle in 1668, it was decided to build a stone castle to protect the city. The construction of Castillo de San Marcos began on October 2, 1672 by the Spanish army when it was part of the Spanish Empire.
 
Castillo de San Marcos is a star shaped fortification built with coquina, a variety of limestone. The workers were brought from Havana, Cuba. The coquina was extracted from Anastasia Island, on the other side of the bay, and taken on boats to the construction site. In 1695, after twenty-three years of hard work, the fortress was ready.

 

Construction

Construction began in 1672, 107 years after the city of St. Augustine was founded by Admiral Pedro Menéndez de Avilés in 1565 when Florida was part of the Spanish Empire on the site of an existing Indian village. Over the next 100 years the Spanish built nine wooden forts in different locations to defend the city, following an attack by Francis Drake and his fleet of 20 ships in 1586, followed by an attack in 1668 by the English pirate Robert Searle.

Maria Anna of Habsburg, Queen of Spain, approved the construction of a star-shaped masonry fortification to protect the city. Coquina was used as a building material, a limestone produced from shell sediments. Workers from Havana (Cuba) were used to build the fort, in addition to Native Americans. The coquina was quarried from the King's Quarry on Anastasia Island, in what is now Anastasia State Park across Matanzas Bay from the castle. Construction began on October 2, 1672 and lasted 23 years, with its completion in 1695.

The city of San Agustín was founded by Spain in 1565. During its first century of existence, nine wooden forts defended the position. After the attack by the English pirate Robert Searle in 1667, it was decided to build a stone castle to protect the city. The construction of the Castillo de San Marcos began on October 2, 1672.

Construction
The Castle is a star fortification built with coquina, a variety of limestone. The workers were brought from Havana, Cuba. The coquina was extracted from Anastasia Island, across the bay, and taken by boat to the construction site. In 1695, after twenty-three years of hard work, the fortress was ready.

First British siege
In 1670, the English founded Charles Town (present-day Charleston, South Carolina) just two days' sail from St. Augustine. In November 1702, forces under the command of Carolina Governor James Moore set out to conquer the city of San Augustin. The 1,200 residents of San Agustín resisted the attacks for two months, sheltered inside the castle, along with the garrison of some 300 soldiers.

The English artillery was not effective against the castle walls, thanks to the coquina, which proved very effective in absorbing the impact of the bullets, and a fleet from Havana forced the British to burn their ships, to prevent them. were captured, and to retreat by land. Before leaving they set fire to the city, which was largely destroyed.

Second construction period
After the siege of 1702, the Castle was rebuilt under the direction of the engineer Pedro Ruiz de Olano. The interior was redistributed and the wooden ceilings were replaced by stone vaults. The walls grew two meters.

Second British siege
In 1739 the Asiento War broke out. General James Oglethorpe laid siege to the castle again and blocked the mouth of the Matanzas River, hoping to surrender it with a continuous bombardment. However, a small Spanish ship was able to evade the blockade and notify Havana, from where supplies were sent. After 38 days the English ended the siege without having managed to surrender the castle.

To protect the Castillo de San Marcos from future dangers and avoid a siege by land, it was necessary to protect the entrance to San Augustin through the Matanzas River. For this purpose, Fort Matanzas was ordered to be built (in English: Fort Matanzas National Monument), which prevented future land raids against the San Marcos fort.

British occupation
By the Treaty of Paris (1763), which ended the Seven Years' War, Great Britain obtained Florida in exchange for returning Havana and Manila to Spain. The Castle lost its strategic importance until the American Revolution. St. Augustine became the capital of the British colony of East Florida. The fortification was improved as a base of operations for the British army in the south and was used as a prison.

With the Treaty of Paris (1783) and the end of the American War of Independence, Florida was returned to Spain.

Second Spanish period
Spanish sovereignty over Florida was only maintained until 1819, when by the Adams-Onís Treaty Florida was ceded to the United States. In this period the castle did not take part in any military events.

First American period
The Americans renamed the castle Fort Marion. There were few changes, although some warehouses were converted into cells, which were used during the Seminole Wars.

American Civil War
In January 1861 at the beginning of the American Civil War, Florida seceded from the United States. The garrison abandoned the fort and the Confederate army occupied it without a single shot. The artillery was dismantled and sent to other locations, leaving the castle defenseless.

Second American period
The castle and town were recovered by the warship USS Wabash which entered the bay on March 11, 1862 without encountering resistance. The castle continued to be used as a military prison throughout the 19th century. In 1900 it lost its military status and in 1924 it was declared a national monument. In 1942, it recovered the original name of "Castillo de San Marcos".

 

Structure

The fort, which covers an area of 1.29 km² and is managed by the National Park Service, has four bastions named San Pedro, San Agustín, San Carlos and San Pablo, with a ravelin protecting the fortified exit. On the two sides towards the land side two glacis were built which forced the attackers to proceed against the cannons of the fort and which allowed the cannons to hit multiple targets in descent. Surrounding the fort was a moat which could be flooded to a depth of one foot (0.3 m) at high tide with salt water from Matanzas Bay before an attack by means of a bulkhead built into the embankment towards the sea.

Several loopholes were built in the curtain wall on the top of the fort and on the ramparts for the installation of cannons of different calibres. Infantry loopholes were built in the wall below the embankment for the deployment of musketeers from the defenders of the fort. It was through one of these loopholes that twenty captive Seminoles escaped in 1837.
