Polaria is the world's most northerly aquarium in Tromsø, Norway. It is designed to be an educational experience, with particular emphasis on displays for children. The museum design represents ice floes that have been pressed up on land by the Arctic seas.
Its centerpiece is an open pool containing a group of bearded seals. The seal enclosure has observation blisters set into its sides, so that visitors can look up at the animals from underneath, and a submerged walkway in a transparent tunnel across the bottom, allowing close access to the animals in their natural environment.
