Hull's biggest tourist attraction is The Deep, Britain's most spectacular aquarium, housed in a colossal angular building that appears to lunge above the muddy waters of the Humber like a giant shark's head. Inside, it's just as dramatic, with echoing commentaries and computer-generated interactive displays that guide you through the formation of the oceans, the evolution of sea life, and global conservation issues.
The largest aquarium tank is 10m deep, filled with sharks, stingrays and colourful coral fishes, with moray eels draped over rocks like scarves of iridescent slime. A glass elevator plies up and down inside the tank, though you'll get a better view by taking the stairs. Don't miss the cafe on the top floor, which has a great view of the Humber estuary.
