Mills in Altoaragón - harinero, central eléctrica


Nocito definitely is a nice spot.
1) From Sabiñánigo drive south to Huesca until you reach Lanave. Turn left where Boltaña is signposted. Don't miss the branch towards Nocito.
2) From Boltaña cross the Río Ara and follow directions for Lanave. It will take some time but eventually you will reach the Molino de Escartín. Now look for the Nocito branch to the left.

From here on it's still 12 km of dirt road. You won't need a 4x4 vehicle when the weather is dry. Park the car near the crossroads where Bara is signposted. Walk the short stretch and take the opportunity to visit the presa on the Río Guatizalema. Nocito has a camping site.

The mill of Nocito is in fact two mills: a powerstation (left) and a flour mill.

The power was turned on for the first time in March 1926! People dragged the turbine 12 km from the Molino de Villobas. The powerstation was the property of a society of most of Nocito's inhabitants. The network was limited to Nocito and the santuario de San Úrbez nearby.
This old generator produced continuous current (DC).

The powerstation was shut down in april 1960 when the number of inhabitants dropped below the critical minimum to continue the maintenance of the turbine.

The village council in 1972 decided to install a new power station on the same place. The first alternating current (AC) left the building on Christmas of that year. This new powerstation stayed in use until deep in the 1990s when pylons reached Nocito. The engine is still ready to run.

The harinero is muy ruinoso and a humble one-room construction. We found similar mills in Aso de Sobremonte and Sarsa da Surta, but Nocito's is the smallest.

At the inside we recognize the cabra, the controlling wheel of the levador and an octangular guardapolvos (as in Almunias de Rodellar).

The cárcavo, ready to collapse, hides a metallic rodete.

Both mills share the same water works. They get water from the same inlet on the Rio Guatizalema. They use only one reservoir and both outlets come together in one channel. Only the section between the reservoir and the cárcavo is private. The blue line on the first picture shows the position of the embalse high on the hill. It's fed by a spacious channel coming from the presa north of the village. The canal to the harinero is open (right on the picture). The powerstation features a closed canal.
