フォートキャロラインナショナルメモリアル

Fort Caroline was an attempted French colonial settlement in Florida, located on the banks of the St. Johns River in present-day Duval County. It was established under the leadership of René Goulaine de Laudonnière on June 22, 1564, as a new territorial claim in French Florida and a safe haven for Huguenots.

The Battle of St. John's Bluff was fought from October 1–3, 1862, between Union and Confederate forces in Duval County, Florida, during the American Civil War. The battle resulted in a significant Union victory, helping secure their control of the Jacksonville area.
