Underwater observatory Maelström

Submerged 17-feet below sea level, Norwegian underwater window restaurant “Under” takes guests on an unmatched sea life dining experience hailed as the world’s largest underwater restaurant and the first in Europe. The three-story establishment opened its doors on March 20, 2019.

This experience is made possible through a 36-foot panoramic window crafted, manufactured, and installed using our acrylic underwater window panels.
