Several mills and oil presses existed in the area surrounding the river Vero, as grains and olive oil were food staples.
To the north, the population and harvests were small, so flour mills were not abundant and only operated when the river flow was sufficient, as was the case of Pedro Buil's mills between Paúles de Sarsa and Sarsa de Surta and the mill at Almazorre (which also has a tile mill and an oil mill) or the impressive mill at Lecina located at the start of the Vero canyon.
Their largest concentration is in the village of the foothills, especially in the area surrounding Barbastro and Alquézar. The area of fields dedicated to grains and olive trees used to be much greater. Since the Middle Ages, several flours mills have existed, such as Fuendebaños in Alquézar and several in the city of Barbastro (among those that survived, the one called “Moliné”, was converted into a La Verense flour production facility).
With respect to the olive oil presses, the Torno de Buera has been restored and converted into the Somontano Olive Oil Centre.
Torno de Buera and the Betorz have also been restored. Others have remained in use, such as those in Alquézar and Adahuesca.
