The Georgia Aquarium, located in Atlanta, Georgia at Pemberton Place, is billed as the "world's largest aquarium" with more than 8.1 million US gallons (31,000 m³) of marine and fresh water housing more than 100,000 animals of 500 different species. The aquarium's notable specimens include four young whale sharks and three beluga whales.
Funded mostly by a $250 million donation from Home Depot founder Bernie Marcus, the aquarium was built on a 20 acre (81,000 m²) site north of Centennial Olympic Park in downtown Atlanta. Marcus credited his 60th birthday dinner at the Monterey Bay Aquarium in 1990 as among the inspirations behind his desire to build an aquarium in Atlanta.
In November 2001, Bernard Marcus announced his idea to build an aquarium as a present to Atlanta, Georgia that would encourage both education and economic growth. Marcus and his wife Billi visited 56 aquariums in 13 countries to research and design a structure, and finally donated $250 million toward Georgia Aquarium’s construction. Due to financial contributions from AirTran Airways, BellSouth, Georgia Pacific, The Home Depot, Southern Company, Turner Broadcasting System, Time Warner, SunTrust, UPS, and the Coca-Cola Company, the company opened debt free. After 27 months and with 60 animal habitats, 16,400 square feet (1,520 m2) of ball room space, 2 food service kitchens, gift shops, a 4-D theater, an on-site restaurant, and a parking lot, the Georgia Aquarium opened first on November 21, 2005 to annual pass holders and then on November 23, 2005 to the general public. At $26 per adult, $21.50 for Seniors, and $19.50 for Children, the price of admission to the non-profit aquarium is among the most expensive in the country. The aquarium has nevertheless far exceeded visitor expectations, welcoming its 1 millionth guest on March 1, 2006, only ninety-eight days after opening. The aquarium sold over 290,000 annual passes for its first year, before sales were halted (to avoid a "private club" atmosphere, according to Aquarium Executive Director Jeff Swanagan). The Georgia Aquarium welcomed its three millionth guest on August 24, 2006 and its five millionth on May 23, 2007.
