A 57-acre property located on the Intracoastal Waterway immediately adjacent to the State Road 312 bridge onto Anastasia Island, Fish Island was once home to the plantation owner, Jesse Fish in the 1700s. It was the first orange grove in Florida and gave birth to the citrus industry. At one time, there were approximately 3,000 orange trees on the island, and the citrus was exported to England and Spain.
Fish Island now represents some of the last undeveloped waterfront property in the City of St. Augustine. The area comprises uplands, which support a maritime forest and a bald eagle nest, and wetland areas, which support an extensive marsh habitat located on the Matanzas River. Fish Island has been listed on the National Register of Historic Places since 1972.
