"Giants of the Galápagos was opened in 2009 to coincide with the 200th birthday of Charles Darwin,[34] and is home to three female Galápagos giant tortoises named Dolly, Polly and Priscilla. The exhibit features a large indoor area, with a heated pond and underfloor heating, while the outdoor paddock has been designed to mimic the tortoise's natural environment and features two heated pools, one of which is a naturalistic clay wallow."
