Italian Artist Christo is funding a $15 million art project on one of Italy’s least known big lakes, Lake Iseo. The project consists of 220,000 floating poly-ethylene cubes that form a walkway inches above the water, connecting a series of islands to the mainland. The exhibit is free and is expected to host over half a million visitors that will make the trek across the water to the other islands.

Check out all of the images and video below as the project continues to be built as we speak!
