In the 13th century, the Ansó valley was made up of five villages: Ansó, Fago, Arahuas, Ornat and Cenar. Of these, only two survive to this day and between them they share the territory with Fago managing a fifth and the other four fifths corresponding to Ansó. The system for managing the municipal area is unique with both municipalities controlling the land but not the villages. Thus, Zuriza and Guarrinza belong to both Ansó and Fago. The very ancient and complex rules governing the administration of the valley have remained in place even in such cases.

The entire village of Fago (888 metres above sea level)may be considered of special architectural interest. Its broad, cobbled streets, its houses, its church, are all outstanding examples of local architecture. The importance of cattle and sheep farming is evident in its sociological and administrative organisation and in its history.

The women of the village of Fago, like those of Anso, Roncal or Urdues, migrated with the seasons like swallows. They would cross the San Miguel Pass in the autumn to go and work at the espadrille factory in Mauleon (France) or as servants in French households, coming home in the spring when the flocks and herds returned to the village from their winter pastures in the lowlands. Fago, situated on the banks of the Majones river, is the village which is furthest from the administrative capital in Jaca and is one of the most sparsely-populated parts of the Jacetania area. As a result, its landscapes are virtually untouched and cater to a more selective tourist.

One of the most exciting leisure activities available is the descent of the Fago Gorge, a short but steep gully which is best negotiated during the spring when it is full of water.
