Polaria is the world's most northerly aquarium. It is located in Tromsø, in northern Norway. Rather than a mainly scientific aquarium such as the one in Bergen in the Norwegian midlands, Polaria, which opened in May 1998, is designed to be an educational experience, with particular emphasis on displays for children. The building itself is also worthy of note. Its striking design represents ice floes that have been pressed up on land by the rough seas of the Arctic. This attractive piece of modern architecture echoes the Arctic Cathedral across the harbour in Tromsdalen on the mainland.
