The 20th Century radically transformed the balance of the alpine landscape by building impressive hydraulic dams, that became the Modernist pride of Switzerland. They changed the country by providing energy to the cities located in the valleys below. Today, these dams bare witness to a foregone era, when glaciers and snow covered peaks were abundant and thought of as the eternal water providers of the nation. Yet all these glaciers are melting rapidly nowadays, and bountiful water will probably be sorely missed soon. Whether the monuments of modernity will take on a new significance in the course of renewable energy strategies is yet to be seen.
