What is it? The Sea Life centre in Brighton is in the world’s oldest operating aquarium.
Why go? It’s hard not to be taken aback by the striking original Gothic arches as you enter this building, which dates back to 1872. We particularly like the Lagoon, populated with beautiful stingrays, and the interactive rock pool where you can touch a starfish or sea anemone.
Don’t miss: The aquarium’s latest attraction, ‘Day and Night’, lets visitors experience a coral reef as it moves through the day into night, thanks to £2.7 million refurbishment.
