Incrementally built between 1847 and 1869, Fort Clinch played a pivotal role during the Civil War, eventually serving as a base of operations for the Union in the region. Utilized periodically during the Spanish American War and World War II, it was restored to the Civil War era during the Great Depression. In 1935, the fort and 256 acres of surrounding property was acquired by the State of Florida. In 1938, Fort Clinch State Park was officially opened to the public. In 1972, the fort was added to the National Register of Historic Places.

Fort Clinch Road links the Fort Clinch State Park with Atlantic Avenue in Fernandina Beach.
