A cool timelapse video from Dezeen shows the world's largest underwater restaurant being submerged in Norway. Check it out above.

The Under restaurant, which we covered earlier this month, is a 5,300-square-foot gourmet restaurant 16 feet below sea level. 

Oak is featured throughout the restaurant. An untreated oak-clad entrance, interior panels, and a giant oak staircase all work to create a warm atmosphere and stave off claustrophobia. Concrete walls 19 inches thick provide resistance from waves and water pressure.
