Mills in Alto Aragón - harinero, central eléctrica
deep in the valley that it gives its name.
From the main road between Sabiñánigo and Biescas, follow directions
for Larrés and the Museo del dibujo. Take left when you reach Larrés
and follow the road below the village. You now enter the valley
of the Rio Aurín and will pass several bore holes for natural gas.
Be ready for some potholes. You will cross the river after some time and
eventually reach Acumuer. Park the car in the penultimate hairpin before
the village. Don't block the gravel road! Walk along the gravel road. At some point you
will cross the GR
. Follow the GR-markings and descend into the
riverbed. Once down, walk against the stream until you reach the mill.

Overview of the site with pressure pit, tube, pond and mill
Front with outlet and the right cárcavo
Not much of a difference between in- or outside
he mill is situated in the bed of
the rio Aurín
on a low platform. Thick walls behind the mill must
break the current and protect the construction against drift-wood and
boulders. The protection dams are broken and some impressive trees
are swept against the remains. One day or another dams, mill and everything will be
The façade bears an
inscription - 1763 - above the entrance. The outlet is at the right side.
Both cárcavos open in the same drain. They are very deep and reach
the backwall of the mill. The cárcavo left is for the power generator.
ome of the old machinery lies shattered all over the workfloor.
The red arrow indicates two mill stones of the harinero. The yellow arrow
points to the turbine for the power generator and the blue arrow shows the tube
feeding the turbine.
Notice how both currents cross each other.
The water for the flour mill comes from the right, from the balsa and
flows to the left. The water for the generator comes from behind, goes to
the turbine near the outer wall and then turns left to the drain.

Pond (embalse) behind the mill - person gives depth
Only the cárcavo of
the flour mill is accessable. The other opening is for the bigger part hidden behind debris.
We found nice masonry housing a metallic rodete and ditto
The balsa leans against the back wall
of the mill. The deepest point in the corner with the saetín is about two meter.
One of the containment walls is an extension of the back wall.
The other, perpendicular on the first, runs parallel with the river.
The channel enters the balsa at the outer end of this wall. Only the
last few meters are preserved. The rest is taken by the river.
Turbine number 156
he turbine carries several
inscriptions. It's a number 156. The other side says La Electricidad S.A. Sabadell
The waterworks of the power station are most impressive. It's a pitty nobody
seems to care for it.
The water is not taken from the river, but from a
small tribute rivulet high on the right bank. A new maintenance road was built
exactly through the capture point and only some diffuse traces survived.

First part of channel is closed

ost of the rest
of the channel still exists and is extremely well built.
The first part of the channel is
closed with flat stones making it immune for blockage by fallen rocks.
The channel continues for several hunderds of meters and then drops
below an old path (connecting village and pastures) to discharge into
an immense reservoir (cubo).
A tube brings the water down to the turbine.

A tube carries the water to the turbine.
