Mills that make the landscape

In the area of the Pyrenees-Monte Perdido World Heritage Site, there are few traditional edifices such as mills connected with the harnessing of the power of water. This is because the valleys are extremely narrow and have very steep sides, making it difficult to get access to the water courses and because of the traditionally limited production of cereals in these valleys.
One of the most outstanding mills is Aso Mill in Aisclo Canyon, since the natural beauty of the place is enhanced by the cultural importance of the edifice, creating an impressive landscape of great significance.

Aso Mill stands on the left-hand bank of Aso Gully, just a short distance from the point where it meets Bellos River and downstream of Aso Falls, one of the most popular spots in the Pyrenees-Monte Perdido World Heritage Site.
Visitors will find few similarities between this part of the gorge today and the way it was in the 1960s. Even more unrecognisable are the photographs taken here by the Frenchman Lucien Briet at the start of the 20th century.

Grain was milled in the small Aso Mill until 1965, when the neighbouring village of Sercu was abandoned. It was later put to new use producing electricity for the towns and villages in the Vi Valley until 1970.
At that point, the mill stopped running and was vacated. The building is now in ruins, with just the walls still standing.
The simple building is almost completely hidden amid dense vegetation and the main elements that gave meaning and quality to this landscape have virtually all disappeared.
