You cross a footbridge to reach this glass-and-stone complex, which rises from the river. With 25,000 fish, seabirds, and mammals, it's Europe's largest aquarium and the first ever to incorporate several ocean habitats (North Atlantic, Pacific, Antarctic, and Indian) in one place. You view the connected tanks and display areas from above and then from underwater; clever use of acrylic walls means that tropical fish and penguins look as if they inhabit the same space. Displays tell you more about the environments you're experiencing, and at the end you can sink onto a bench in one of the "contemplation" areas and just watch the fish swim by.
