L'Oceanografic, Valencia, Spain

This aquarium in Valencia, Spain's City of Arts and Sciences district, is arguably one of the most unusual venues of its kind on the planet. L’Oceanogràfic's main building, with a curving roof and huge windows, is an attraction in its own right. The aquarium is made up of separate wings dedicated to different ocean ecosystems. It also has a dolphinarium that hosts training sessions and performances, and habitats for unique creatures such as walruses, penguins and beluga whales.
