People once flocked to Radium Springs to swim in its crystal-clear blue natural pool. American Indians called the spring "Skywater," and white settlers called it "Blue Springs." Developers in the early 1900s built a restaurant and guest cottages, followed by a grand Casino completed in 1927. Despite its name, the colonial-style Casino offered entertainment rather than gambling, with an elegant dining room and a cavernous dance hall set atop terraced stone walls rising from the pool. Guests enjoyed lavish meals, dancing, moonlit canoe rides, swimming, and daytime activities such as golf, horseback riding, hunting, and tennis, while underwater lights revealed eels, fish, and turtles. Lab tests in the 1920s found traces of naturally occurring radium in the water, leading to the name Radium Springs. The spring remained 68°F year-round, and just 4 miles from Albany, Georgia, the resort hosted golf tournaments, galas, and beauty pageants during its glory years. During World War II, the Casino served as an Officer's Club for the Army Air Corps. A fire in 1982 and floods in 1994 and 1998 damaged the Casino beyond repair, and the remaining structure was removed in 2003. Radium Springs is one of the Seven Natural Wonders of Georgia, and the grounds around the spring have since been reborn as a botanical garden.
