In 1564 French explorers founded the first Protestant colony in the US along what is today the St Johns River. This reconstructed fort commemorates its probable location. The Spanish seized the original colony and massacred its residents in 1565, so not much is known about these early pioneers. The site stretches across 130 acres overlooking the river and features a museum with French and Indian artifacts from the 16th century. Fort Caroline was established as a national memorial in 1950 and is 14 miles from downtown Jacksonville.
