Cecil B. Day Butterfly Center at Callaway Gardens

North America's largest glass-enclosed tropical conservatory opened at Callaway Gardens on September 25, 1988, named for Cecil B. Day, founder of Days Inn, whose widow donated artwork and financial support in his honor. The 7,300-square-foot dome rises 35 feet at its peak and maintains roughly 80°F and 74% humidity year-round, sustaining over a thousand butterflies of more than fifty species alongside 250 plant varieties. Butterflies arrive as chrysalises from farms in six countries. The center earned LEED certification in 2004 and underwent a $2 million renovation in 2005.
