Coll

Coll appears in written records for the first time in 1054, listed among the villages that made up the territory of Castilló de Tor, which had been purchased by King Ramiro I of Aragon. His son, Sancho Ramírez, then handed ecclesiastical authority over the territory to the bishopric of Roda de Ribagorça. Coll remained part of Castilló de Tor for a long time, and when the Roda bishopric was eventually dissolved, it passed into the diocese of Lleida, where it remains today. A 1553 census recorded 13 households in Coll, roughly 65 people.

The geographer Pascual Madoz described the village in his 1849 dictionary. He found 15 stone-fronted, timber-framed single-storey houses, all modest, on uneven unpaved streets. The parish church of Santa Maria had a resident rector, and a small hermitage was dedicated to Sant Antoni. Water came from a nearby spring and a stream about fifteen minutes' walk away. The land was mountainous, dry, and rocky. Farmers worked around 130 days' worth of plots, growing rye, potatoes, and pulses, and raising sheep and goats. There was also a flour mill, and hunters could find partridge and rabbit. Madoz counted 12 heads of household and 69 inhabitants in total.

In September 1907, Coll was one of the stops on an archaeological and legal survey along the Aragonese border, organised by the Institut d'Estudis Catalans to help protect Catalan artistic heritage. The team included the architect Josep Puig i Cadafalch, along with Josep Gudiol, Guillem Marià Brocà, Josep M. Goday, and the photographer Adolf Mas.

Today Coll is a small village within the municipality of the Valle de Boí, at an altitude of 1,180 metres, with distant views of the Cardet reservoir and the town of Barruera. The municipality of Vilaller lies to the west, along the banks of the Noguera Ribagorzana river.
