We continued our tour of Swiss infrastructure on a Thursday morning by driving down our mountain, across the valley, and up another one to reach the country’s tallest dam, the Barrage de la Grande Dixence. Built over a period of 14 years from 1951 to 1965, the dam replaced a smaller one that was completed in 1935.

Today the water stored in the dam helps generate electricity for some 400,000 Swiss households.

We got to tour inside the dam, where it was cold, dark, and confined (claustrophobics need not apply) before visiting the top of the dam and then hiking along the western side of Lake Dix.
