Discovering the ancient mills
In Val Rogna, on the boundary with the municipality of Chiuro, on the left bank of the municipality of Teglio, traces are still visible of ten water mills that were in activity from the 17th to the 20th centuries. The toponym Rogna seems is refer to water, but also to the disputes between the two municipalities over its use, which was necessary to move the millstones. Water and mills are, in fact, the characteristic elements of the valley, immersed in luxuriant vegetation. The statistical annals of the Province of Sondrio reveal that in 1886 “there were 523 mills for grinding cereals spread out over 72 municipalities, with a hydraulic force of 457 hp and employing around 800 workers. The product is calculated to be 16,746 quintals, of which 1109 of wheat, the rest maize, rye and fraina (buckwheat)”. The municipality with the most mills was Teglio, with no less than 38! This demonstrates how wheat, and rye in particular, was the fundamental element of a typical alpine diet, rich in fibres and poor in fats.
