Eiffel Tower's "Face-Lift"

Vertiginous glass walkways are becoming a 21st century means of luring even more tourists to well-known places, as evidenced by The Ledge at the top of Willis Tower in Chicago, the horseshoe-shaped Grand Canyon Skywalk in Arizona, and the incorporation of a circular glass-floor observatory in the cantilevered prow of OMA's CCTV Headquarters in Beijing. In the case of the Eiffel Tower's glass floor, it is one part of a first-floor redevelopment that also includes rebuilt reception and conference rooms as part of its event space, rebuilt visitor services, and a "museographic path." Moatti – Rivière are the architects responsible for the face-lift whose diagonals and transparency were inspired by Gustave Eiffel's curved and tapered structure.
