Quick Description: The Spanish Coquina Quarries are located in the Anastasia State Park in St. Augustine Beach, Florida. They were added to the National Register in 1972.

An historical marker at the site provides the following information about the Old Spanish Quarries: "About 200 yards south-east of this point are the remains of the King's Coquina Quarries. (Coquina, a type of limestone composed of mollusk shells and sand, is found along the north-east coast of Florida.) Coquina was used in the building of many early colonial structures in St. Augustine, including the fortress Castillo de San Marcos (1672-1696)."
