The original wheel was built in 1618 to address the water scarcity in the fields of Groppello d'Adda.
The wheel uses a complex system of wooden gears and buckets to raise water to an elevation of approximately 6 meters.
It was meticulously reconstructed in 2009 based on historical records and traditional woodworking techniques.
The wheel serves as an emblem of the agricultural history of the Lombardy region.
It is integrated into the larger 'Ecomuseo Adda di Leonardo', highlighting the proximity to Leonardo da Vinci's historical influence in the area.
The Rudùn, officially known as the Great Wheel of Groppello, is an imposing 11-meter diameter wooden water wheel situated on the Martesana Canal. Originally constructed to lift canal water into the elevated irrigation ditches of the surrounding fields, it remains a rare functional example of 17th-century hydraulic engineering. The current structure is a faithful reconstruction of the original 1618 design, which fell into decay during the 20th century. Its rotation is powered entirely by the flow of the Adda River and the Martesana Canal junction. The wheel's restoration has turned this industrial artifact into a focal point for local heritage preservation. Visitors can observe the wooden mechanics and the flow of the canal water that drives the circular frame.

Combine your visit with a bike ride along the Martesana Canal path for a scenic approach.
Check the local Pro Loco website for potential seasonal maintenance updates before traveling.
Walk across the nearby small bridge to get a comprehensive view of the entire hydraulic mechanism.
Do not attempt to touch the mechanical components or climb the wooden structure, as it remains a functional piece of machinery.
Operates year-round, though functionality may be suspended during winter canal drainage or maintenance cycles.
