BIG has completed a new sculptural observation tower that rises on a beautiful landscape of Denmark‘s Wadden Sea National Park. 

A 25-metre corten steel tower is made of a double helix structure and acts as a sculptural art object rising out of the landscape.

Named Marsk Tower, the structure was opened to the public and will provide a new gathering place in the UNESCO World Heritage site of Wadden Sea National Park.

Marsk tower is a testament to our two decades-long friendship and collaboration with the blacksmiths of Schacks Trapper,” said Bjarke Ingels, Founder and Creative Director, BIG – Bjarke Ingels Group. 

“The double helix provides two stairs and an elevator with a single stack of rotating steel steps, allowing visitors to ascend and descend in a single spiraling loop from the sand to the sky – connecting the marsh land to the Wadden Sea,” Ingels added.
