Mulino del Dosso, Ethnographic museum in Rasura, Italy

The Mulino del Dosso is a stone water mill on the Rio stream, which forms the boundary between Rasura and Cosio Valtellino in Sondrio province. It has two grinding chambers (palmenti) and a wooden water wheel fed by a channel; the vertical shaft turns the toothed wheel that drives the upper millstone. The restored building now houses the Vanseraf ethnographic museum.

Giovanni Pezzini built the mill in the first half of the 19th century, and a wall inscription records that Giacomo Pezzini's mill was built and restored in 1836. It served the valley for nearly two centuries, grinding white flour for bread and cornmeal for polenta. Abandoned by 1997 and at risk of sliding into the Rio, it was bought from the Pezzini family and restored with private funding by Serafino Vaninetti, resuming production in 1999.

The collection displays the tools and equipment that people once used for their daily grain processing work in this valley. You can see how residents approached the task of turning raw grain into finished flour through their inherited methods.

Guided tours allow you to watch the restored machinery in action and observe the complete grain milling process from start to finish. Wear comfortable shoes as the path to the mill and areas inside have uneven surfaces.

The roof was built by specialized craftsmen called Teciàtt using local stone and ancient construction methods that are now rarely seen. This traditional roofing represents a regional building skill that has nearly disappeared in modern times.
