8The Solvay Hut (Switzerland)

Located on the slopes of the Matterhorn in Switzerland, the Solvay Hut is the highest mountain shelter in the region, sitting at an altitude of 4,003 meters (13,133 feet). It’s used as an emergency refuge for climbers, but its isolation and breathtaking location make it one of the loneliest structures in the world. Reaching the hut requires a challenging climb, and its remote position ensures that only the most dedicated adventurers get to experience its solitude.

Why it’s special: The Solvay Hut’s location, perched on the steep cliffs of one of the world’s most iconic mountains, makes it a symbol of survival and solitude.
