How architects built those wildly popular floating piers in Italy

The work consists of a three-kilometer walkway wrapped in 100,000 square meters of yellow cloth

The Floating Piers is the latest and last work of artist duo Christo and Jean-Claude. The floating dock extends over the water of Italy’s Lake Iseo. Here is how they did it. 

The work consists of a three-kilometer walkway wrapped in 100,000 square meters of yellow cloth, which is supported by a floating dock system composed of 220,000 high-density polyethylene cubes. These elements naturally undulate with the movement of the waves at Lake Iseo, which is located 100 kilometers east of Milan and 200 kilometers west of Venice. The floating yellow roads extend from the pedestrian streets of Sulzano, connecting the islands of San Paolo and Monte Isola.

The Floating Piers is the first large-scale work of Christo for more than a decade after making The Gates in 2005 with Jeanne-Claude, who passed away four years later. Due to the importance of Christo and Jeanne-Claude’s work and the inspiration they have given to many architects, we wanted to investigate the process of building this spectacular project, which makes the dream of walking on water a reality.
