The Valley of Arán, where Baqueira-Beret is being integrated, was since historical times populated. Furthermore, as frequently along the Pyrenees, here too, Cesars Roman troops coming from France entered here the Iberian Penisula. The earliest documentation of the area is from the 10th century.

In the year 1175, under the reign of Alfonso II, The Arán Valley starts to be part of the Crown of Arágon. During two or three centuries, this valley was constantly fought about. It was part either of France or the Reign of Aragón until in 1313 the people of the valley decided that their protectorate should be Aragón and not France. It was then, when Jaime II granted a number of privileges to this region, in 1415 he united with the catalan reign.

In 1810, Napolean set food on these grounds, who entered Spain at Puerto de Viella, but in 1815 after Napoleons resignation, the valley regained its previous position under the Spanish Crown.

It was during the XX century, that the Arán Valley developped as we know it today, with new roads, tunnels and railways and the conversion of the region into a natural and tourist ressort.

It was in the 60's when Spain timidly opened its doors towards the exterior, that a group of people in the valley decided to found the first skiing station. The Naut Aran Station, as it was called, enjoyed the best snow conditions possibly hoped for. Its fame reaches across the time until today, where it is still the most visited skiing station of the valley with 10km of slopes and great gastronomic facilities.

Its economy is historically based on the exploitation of its forrests, thus however, having changed to the major resource tourism provides.

As far as culture is concerned, one main issue is the architecture of Baqueiro with its very special houses. Tipical are the "escudos" stone houses with large chimneys. Also, when we exit the valley, very close by we encounter the Valley of Boi, where we find the most important Roman collection of Europe - hence it had been catalogued by UNESCO as a "Patrimony of Humanity". The area of the Alta Ribagorza is considered as the cradle of the Roman art of the catalan Pyrenees.
