Slowly the road winds up through the valley towards the Coll de Bóixols in Catalonia. To construct the road, parts of the mountain were struck off, creating this structure in the bends of the road. Catalonia has a population of more than 7.5 million inhabitants, the vast majority of which are Catalans. The region has a highly developed own identity and by a constitution of autonomy it was recognized as a nation within the country of Spain.
