Surely the most breathtaking stop on this wonderful list of glass madness, the ‘Step into the Void’ experience in the French Alps gives tourists an unrivalled view of the Chamonix Valley.
The glass used to create the five-sided box is 12mm thick, can stand winds of up to 220km/h and is 3842m high on the Aigulle du Midi peak, with Mont Blanc nearby.
The attraction opened late last year and it takes two cable cars to reach it. We imagine a fair few people bottle out before they get to the final view…
