Roman road of Àger
The so-called Roman road of Àger is a traditional road that still preserves some cobbled sections, which linked it with the villages to the south of the Montclús mountain range. It can be followed from Fontdepou to the Pont d'en Rosell, at the entrance to the village. It is likely that it was once one of the paths that linked the Lleida plain with the Pyrenees, just as it was used for centuries as a drovers' trail: the herds travelled along the path from the Boí Valley to Linyola, and vice versa, every year (until the 20th century).
The 2002 archaeological intervention carried out on the occasion of the extension of the C-12 found two types of paving, a more elaborate one with a central spine, and a simpler one without, with two types of dripstone. Neither of the two corresponds to a canonical Roman road, but rather to a medieval work, maintained and remade until recently. The first written references to the road date from the 11th and 12th centuries. However, the path is of obvious historical, archaeological and tourist interest, as it is unusual to find ancient cobblestones preserved.
