New photos show BIG's twisting Marsk Tower

Danish architecture studio BIG has revealed new images by Rasmus Hjortshøj of Marsk Tower, its spiralling double-helix viewing tower that recently opened to the public in southwestern Denmark.
The 25-metre-tower is located in the UNESCO world heritage site of Wadden Sea National Park and was constructed from Corten steel.
