The Expo 2008 (14.06 - 14.09) in Saragossa can be reached over a bridge which officiates as an supersized, futuristic pavilion, which was planned by no less than Zaha Hadid Architects. The entire lighting design, consisting not only of artificial lighting, but also of natural day-lighting, was accomplished by Bartenbach LichtLabor.
