This house was built on impossible terrain at an elevation of 4,003 meters (13,133 feet) in Switzerland in 1915. I wonder what technique was used to get everything up there, above the clouds…

The tallest house in the world is a stopping point for mountaineers conquering the Matterhorn peak in Switzerland.

Solvay Hut is a small wooden house located halfway up the Matterhorn mountain, near Zermatt, in the canton of Valais, Switzerland.

With an altitude of 4,003 meters, it is the highest mountain refuge in the world. Its main function is to provide food and a resting place for mountaineers.

However, Solvay Hut can only be used in emergencies. It is located above the Hörnli hut, about 743 m and 475 m from the top of the mountain.

Many climbers who conquer the Matterhorn peak stop in front of the Solvay Hut to admire the landscape of the Monte Rosa mountain range.

The Solvay shelter was built in 1915. The materials were brought to the Hörnli shelter by pack animals and from there the materials were transported by a temporary cable system to an altitude of more than 4,000 meters.

The house was built in just 5 days. In 1966 it was rebuilt and in 1976 an emergency telephone station was installed.

The house is named after Ernest Solvay (1838-1922), Belgian mountaineer, explorer and businessman. Solvay also provided funds for the construction of this facility.
