The Cecil B. Day Butterfly Center is located at Callaway Gardens in Pine Mountain, Georgia. It is North America's largest glass-enclosed tropical conservatory. The center was named in honor of Cecil B. Day, a philanthropist and the founder of Days Inn. His wife, Deen Day Sanders, donated artwork and financial assistance to Callaway Gardens in his honor. Opening in 1988, the center houses over a thousand butterflies of over fifty different species.
