Mills in Alto Aragón — harinero


Alquézar is easily reached from Huesca and Barbastro. Halt just before entering the village at the Ermita de San Antonio and walk the dirt road down. Or, from the village center, follow the signposts fuente (mineral spring). Old maps show this mill as Molino de arriba (the upper mill). The mill is on the Río Vero. We had the luck that the owners of this mill invited us for a photosession inside.

seen from Ermita de San Antonio
(2) The mill proper is rightmost building
with cárcavo just visible.

Quite a steep descent, but once down there You will agree that a visit is worth every gasp on the way back. The construction is very well preserved thanks to the efforts of the present owners who bought the mill from the last miller in the 1960s.
The mill proper with all the machinery is the right­most part on the picture. The cárcavo indicates that the floor inside lies above ground level outside. The necessary steps are made from old mill stones.
Walk past the mill and long the river towards the enormous barrage (azud, 3, 4). There is more than its size that strikes the eye. The central part is much higher than the rest. Close inspection reveals that the wall is solid and not a leftover of a bigger wall closing the complete river bed.
Better still, left and right half are not in line with each other. The barrage left from the central wall protrudes considerably.

(5) Central section of azud
Antonio Naval Mas, in his work about historical constructions in the Somontano region, devotes several pages to his educated guess about the meaning of this peculiar ground-plan. It probably was the base of a batán. (Visit Abiego for another impressive dam.)

The channel takes its water from the right bank of the lake, about 20 m before the barrage. The inlet is protected by a grating. The first few meters are tunneled through the rock.

(7) Grating keeping logs out.

The rest of the canal is wide and open. It passes the azud and at that point the wall features a nice pointed arch with a valve to drain superfluous water. From the azud to the mill a broad and high earthen wall has been thrown up. The largest part of the supply channel was dug out in this dam.
The canal ends in a reservoir made from excellent masonry (in fact much better than the rest of the construction). The water is drained through three funnels, saetines, deep below the floor of the reservoir (remember, we need sufficient pressure!)

(8) Earthen wall supporting the canal.
(9) Balsa with three inlets.

As a consequence we would expect three outlets on the other side of the building, but that's not true. The southern wall shows only two arches (11). It all becomes clear when we enter the left cavity. It hides two cárcavos each with a pointed arch. Each cavity housed the familiar horizontal wheel.
The last cárcavo features more recent modifica­tions: a small concrete construction with valve and support for a metallic wheel on a horizontal (!) axle. A low ridge keeps the water to one side of the cárcavo.

(15) Mill stone, cabra and dressing tools.
(16) Octogonal guardapolvo with tolva.

The interior is a miller's treasure cave. It would require quite some work to make the mill ready to run, but most of the important things are preserved: machinery, storage, dressing tools. The floor gives plenty of opportunity to study different dressing patterns.

The mill stones are from France. We recognize the mark of Grande Société Meulière Dupety-Orsel & Cie from La Ferté sous Jouarre. (Other stones with the same origin are found in e.g. Cortillas, Paternoy, Sarvisé, Palo.)

(18-19) Mill stone from La Ferté.
