Nature Heritage S.L. has acquired the Hydraulic Mill of Cuña, rescuing from neglect and deterioration one of the most singular historical and ethnographic pieces in the valley of Teverga, a grain mill that remained in active use for more than four centuries in the service of the rural communities of the Asturian mountain interior.

Located in the municipality of the same name, in the parish of Barrio, at the heart of the Biosphere Reserve and Natural Park of Las Ubiñas-La Mesa, the mill dates to the 15th and 16th centuries and is historically linked to the Manor House of Cuña of the Cienfuegos family, one of the most significant and long-established noble lineages of the region.

The opportunity to assume stewardship of a site with these characteristics — singular heritage, ecosystem and ethnographic memory within a Biosphere Reserve — was decisive, and aligned perfectly with our founding values: to conserve and transmit natural and cultural heritage as a received legacy, accepting the responsibility of ensuring its continuity and preservation.

The property comprises the mill building with its hydraulic mechanism in a remarkable state of conservation, and the surrounding estate of high environmental value, fed by two streams whose confluence was the original criterion for the mill’s location five centuries ago.

What makes this mill a truly exceptional piece among the hydraulic mills of Teverga is the combination of circumstances that rarely converge in a single property:

• It is the only mill with documented manorial provenance.
• It belongs to the category of horizontal wheel hydraulic mill with a pit wheel system (an adjacent structure housing a vertical column of water to generate hydraulic pressure by gravity), with the delivery pipe embedded directly into the stonework of the wall — without the need for an independent external channel. This solution represents the most evolved and refined form of the pit wheel system, technically more demanding to construct but more efficient and fully integrated into the structure.
• It retains the entirety of its principal original mechanism.
• Its bedstone, an unworked natural stone, represents the most ancient tradition of Iberian hydraulic milling.
• Its location at the confluence of two watercourses ensured the mill approximately eleven months of annual operation.
