Coquina Quarry - Spanish Ruins
Anastasia Island, St. Augustine Florida
Coquina, tiny shells, is a natural seashell rock found in St. Augustine. The Castillo is the most significant
building using this stone, but in St. Augustine 1st, the one remaining British building and 2nd period
Spanish buildings are made of coquina. The Island itself was originally called
La isla de la cantera
(Quarry island) before it was named Anastasia Island. The rock was cut by hand and moved to Quarry
creek and floated across the bay to the Castillo and city.

The men who worked there were varied in their backgrounds including people from all over the
Spanish Empire, Native Americans, Africans, and captured prisoners. An Englishman was actually the
quarry master at one time in the Spanish rule.

In 1763 King George III declared the quarry pits to be a royal reserve.

In Victorian St. Augustine the rock was used in its gravel form with concrete to build: the Ponce de
Leon Hotel, Alcazar, Casa Monica, Villa Zorayda, Grace United Methodist Church, Memorial
Presbyterian, and other buildings. Henry Flagler used the actions of the tide to move the gravel across
the bay.
