Anastasia State Park is a 1,600-acre (6.5 km2) state park in Florida, United States. Its location is on a peninsula on Anastasia Island across Matanzas Bay from downtown St. Augustine along the Atlantic coastal plain. This park has a variety of wildlife, birds and plants in a setting of beaches, tidal salt marsh, and marine and upland hammock. It is also home to the Old Spanish Coquina Quarries, an archaeological site from which the coquina stone used in the construction of the Castillo de San Marcos in St. Augustine was mined, earning it a spot on the National Register of Historic Places. Acquired by the state of Florida in 1949, Anastasia State Park has long been a favorite playground for hundreds of thousands of visitors each year.
