High up in the French Alps, on the top terrace of the Aiguille du Midi mountain peak, sits a new five-sided glass structure called the Chamonix Skywalk, soon to be open to the public on December 21, 2013. The installation was inspired by the Grand Canyon’s Glass Skywalk, but it takes the concept to the next level. Instead of looking out over a railing, visitors can hover 1,035 meters (3,396 feet) above the valley in an enclosed transparent box, surrounded on all sides by custom-made 12 mm (1/2 inch) glass. The Chamonix Skywalk is a five-sided glass structure– three layers of glass bound together–with a 1,000 metre drop below, where visitors can step out from the terrace, giving the visitors the impression of standing in the void and is the latest addition to the ongoing improvements being made to the Aiguille du Midi. The box can withstand winds of 200km/h (136mph).

The structure is made entirely of glass to allow for maximum transparency, three glass plates of 12 mm each are binded with a transparent film of the five faces, all held together by mechanical fasteners. The unit is then fixed to a vertical support structure over the void. The Chamonix Skywalk gives visitors an incredible positioning atop the Aiguille du Midi mountain.
