The St. Johns Light Station was built in 1954 to replace the St. Johns Lightship (LV-84). When the St. Johns River lighthouse was decommissioned in 1929 it was replaced by a lightship stationed 7 miles east of the mouth of the St. Johns River. The St. Johns Light is made of concrete, poured in one continuous operation. It has never had a traditional lantern, but received an airway-beacon style light from the beginning.
