Once a part of Duval County (Jacksonville), Clay County was carved out on December 31, 1858. The
county consists of our incorporated municipalities: Orange Park, Green Cove Springs, Penney Farms, and Keystone Heights,
as well as one unincorporated municipality, Middleburg.
Both regional and national wars greatly impacted life in Clay County. When fighting erupted with the Seminoles in
December 1835, Garey's Ferry (the site of present-day Middleburg) was chosen as a supply depot for the US Army on
Florida's east coast. In 1836, Ft. Heileman was established and Gary's Ferry was one of the few Florida frontier towns
not abandoned during the 2nd Seminole War. As the Civil War was nearing its end, Clay County saw its first battle. In
mid-1864, Union forces established a fort at Magnolia Springs on the St. Johns River where they could send troops to
apply pressure to Confederate forces located within the county. While Union troops were returning from a successful raid
on Middleburg, Confederate forces under the command of Capt. J.J. Dickinson engaged the Union troops and inflicted heavy
casualties. The battle lasted 45 minutes with no casualties among the Confederate troops.
After the Civil War, tourism became a vital part of Clay County life. Northerners were drawn to natural springs that
promised healing and warm winter climates that offered respite from frigid northern winters. The tourists were delighted
by the exotic wildlife and vegetation found along the banks of the creeks and rivers. Dozens of hotels were built to
accommodate the visitors who came by steamboat. Hotels such as the St. Elmo, Magonlia Springs, Clarendon, and the
Oakland Hotels invited tourists to rest and relax in the sunny climate of Florida. Families along the St. Johns River,
such as the Flemings, opened their plantation homes to northern visitors. Among the visitors to Clay County were such
famous people as Ulysses S. Grant, President Grover Cleveland (who had spring water shipped to the White House), Buffalo
Bill, and Sitting Bull. The height of tourism in Clay County spanned three decades, from the 1870's to the early 1900's.
Tourism in Clay County went into decline when Henry Flagler's railroad reached Miami, and south Florida was easily
accessible.
As reported by the Census Bureau, the county has a total area of 644 square miles (1,667 km2), of which, 601 square miles (1,557 km2) of it is land and 43 square miles (110 km2) of it (6.62%) is water.
