The Deep - 'the world's only submarium'

The Deep is a large underwater aquarium situated at Sammy's Point, at the confluence of the River Hull and the Humber estuary in Hull, England. It opened in March 2002.

Billed as 'the world's only submarium', the tank contains thousands of sea creatures (including seven species of shark), 2.5 million litres of water and 87 tonnes of salt housed in an iconic structure designed by Sir Terry Farrell and built as part of the UK National Lottery's Millennium Commission project.

So far the deep has welcomed over 2 million visitors from around the world.
