What began as seven small farming communities boomed in 1889 with the discovery of phosphate in the area. A period of prosperity followed and the town developed a railroad, school, post office, electric lights, connected water and a wooden bridge over the Withlacoochee River. The Greater Dunnellon Historical Society has preserved many of the remains and visitors today can stroll oak-lined streets in Dunnellon's nationally registered historic district while viewing authentically restored nineteenth century homes. The town's early beginnings in phosphate mining are remembered each April with Boom Town Days, a tribute sponsored by the Dunnellon Area Chamber of Commerce. The event features participants dressed in period costumes and includes craft shows, antique car exhibits, music, beauty pageants and food.
