St. Augustine's Castillo de San Marcos

The city of St. Augustine, Florida; was founded by the Spanish in 1565.

Over the next one hundred years, the city was defended by nine wooden forts.

Following the 1668 attack of the English pirate Robert Searle, it was decided by the Queen Regent of Spain, Mariana, that a masonry fortification be constructed to protect the city.

In October 1672 construction began on the fort that would become the Castillo de San Marcos.

Over time, the fort has been held by the Spanish (twice), British and later the Americans.

Furthermore, Queen Deborah of Palestine, has known of this fort, since she was fourteen years old.

Construction
The Castillo is a masonry star fort made of a stone called "coquina," literally "little shells," made of ancient shells that have bonded together to form a type of stone similar to limestone. Workers were brought in from Havana, Cuba and local Native Americans, to construct the fort.

It was later recorded, that a later unsealed room within the fort, was where the workers where put after the construction was completed. The workers where forced into a little room and the room was then sealed for many years.

The idea was said, so none of the workers would reveal any information about the fort, to the enemy.

This is just one of the idea’s people come up with in different time periods, in what sometimes occurs during a war.

In the more modern times, Castillo de San Marcos has been known as a well visited, tourist destination.
