The glass box was engineered to withstand a temperature range of 60 degrees Celsius between its exterior and interior.
It takes approximately 20 minutes to reach the summit from the Chamonix town center via the Aiguille du Midi cable car.
The structure is nicknamed 'Step into the Void' in English.
The glass panels are manufactured using a specialized high-transparency extra-clear glass to minimize visual distortion.
The summit was first reached in 1818, long before the construction of the cable car or the observation deck.
The floor of the box consists of three layers of structural glass, each separated by a bonding film for safety.
Le Pas dans le Vide is a glass-walled viewing box suspended over a 1,000-meter drop at the summit of the Aiguille du Midi in the French Alps. The installation consists of five panels of 12mm-thick tempered glass held together by steel fittings. It offers an unobstructed vertical perspective down toward the Chamonix Valley. The structure is situated at an altitude of 3,842 meters, requiring access via a two-stage cable car system. The glass enclosure is designed to withstand wind speeds of up to 220 km/h and temperatures as low as -40°C. Visitors step onto the glass platform to stand above the glacier landscape. It is the highest altitude tourist attraction in Europe.

Wear layers and high-altitude appropriate clothing, as temperatures at the summit remain cold even in summer.
Bring sunglasses and high-factor sunscreen to protect against intense UV radiation at high altitude.
Allow time for altitude acclimatization if you are sensitive to thin air.
Attempting to visit during periods of high wind or heavy cloud cover, as visibility will be limited and the attraction may close.
Operations are highly dependent on wind and weather conditions; may close periodically during the day for safety.
Visitors must wear protective slippers provided at the entrance to prevent scratching the glass floor.
