Natural Bridge is the site of the second largest Civil War battle in Florida and where the St. Marks River drops into a sinkhole and flows underground for one-quarter of a mile before reemerging. During the final weeks of the Civil War, a Union flotilla landed at Apalachee Bay, planning to capture Fort Ward (San Marcos de Apalache Historic State Park) and march north to the state capital. With a timely warning, volunteers from the Tallahassee area-Confederate soldiers, old men, and young boys-met the Union forces at Natural Bridge and successfully repelled three major attacks. The Union troops were forced to retreat to the coast and Tallahassee was the only Confederate capital east of the Mississippi not captured by the Union. A reenactment of the battle is held at the park every March.

The Valiant Air Command is a non-profit museum. The museum displays, maintains and restores all types of aircraft that were indigenous to the world's military Air Forces starting before WW1 to the present. The Main Bay/Display Area contains approximately 30,000 square feet and is wide and high enough to accommodate the wing span and tail assembly of all but the largest bombers. In addition to the main hangar bay, there is an area 15,000 square feet dedicated to the display of memorabilia associated with the "Valiant" individuals who flew, maintained these aircraft.
