Pangeos The Terayacht: World's Largest Floating City

Italian design house Pierpaolo Lazzarini has revealed plans for a gigantic $8bn turtle-shaped terayacht, with Saudi Arabia as the proposed location for the project. If funded, the project would be the world's largest water structure. The boat, Pangeos, a name derived from the prehistoric supercontinent Pangea, could potentially house up to 60,000 guests. The Lazzarini design house is known for its ambitious luxury transportation concepts.
