About Diga del Narèt I
Diga del Narèt I (Italian for “Narèt Dam I”) is a concrete gravity dam situated at the coordinates 46.481768 N, 8.573305 E in the municipality of Airolo, canton of Ticino. Constructed as part of a cascade of hydro‑electric projects, the dam stands 80 metres high, harnessing the powerful Alpine streams that tumble down from the surrounding peaks.
History & Significance
The dam was built in the mid‑20th century during Switzerland’s post‑war push to expand renewable energy capacity. Its strategic location in the Ticino valley allows it to feed water into the regional power grid, supporting both local communities and the broader Swiss energy network. While the exact year of completion isn’t publicly listed, the structure’s robust design reflects the engineering standards of its era—solid, functional, and built to last.
Beyond its utilitarian role, Diga del Narèt I has become a symbol of the harmonious coexistence between human ingenuity and nature. The dam’s concrete façade mirrors the surrounding rock, and its reservoir creates a tranquil mirror that reflects the towering peaks, making it a favorite spot for photographers and nature lovers alike.
