Blue Planet Aquarium

The Blue Planet Aquarium is a marine and freshwater aquarium located by the Cheshire Oaks retail and leisure complex in Ellesmere Port, Cheshire, England. When opened by the Queen in July 1998, it was the largest aquarium in the UK, and is still the largest in North West England. The £12 million building was designed by Manchester-based Buttress Fuller Alsop architects to resemble the shape of a crashing wave. It was built by Cheshire-based developer Deep Sea Leisure, who also built Deep Sea World in North Queensferry, Scotland.

Its stated aim is to "enlighten, increase knowledge and raise interest in the marine environment using an interactive, entertaining and sustainable approach."
