Megastructures: Louvre Abu Dhabi

Floating on the shores of the Arabian Gulf, is the Louvre Abu Dhabi. Designed by star architect Jean Nouvel, this Arabic-inspired museum is built is association with the Louvre Paris to house over 400 priceless masterpieces. Shading the gallery buildings is a massive steel dome, weighting 7,000-tons - a feat of engineering never achieved before. The Louvre Abu Dhabi is a visionary piece of architecture, ahead of its time, and quite possibly a work of art in its own right. (National Geographic)
