Bjarke Ingels Group has designed a spiraling double helix structure that acts as a stunning observation tower.
Standing in marshland at Denmark’s Wadden Sea National Park is the striking Marsk Tower. Designed by the renowned architecture firm Bjarke Ingels Group (BIG), the observation deck is inspired by the double helix structure of DNA. The 85-foot (25 meters) tower comprises spiral steps around a central core and acts as both a functional lookout as well as a sculptural landmark for the park.
Visitors to the tower will enjoy unobstructed views of the surrounding landscape including the North Sea. The design of the double helix means that they will traverse 146 steps on the way up and 131 steps on the way down. Each direction wraps around the elevator located at the core of the tower.[…]
