Madriu-Perafita-Claror Valley is a glacial valley in the Pyrenees Mountains of southeast Andorra. The valley added as a UNESCO World Heritage Site for its dramatic glacial landscapes of craggy cliffs and glaciers, with high open pastures and steep wooded valleys, covers an area of 4,247 ha, 9 percent of the total area of the principality. It reflects past changes in climate, economic fortune and social systems, as well as the persistence of pastoralism and a strong mountain culture, notably the survival of a communal land-ownership system dating back to the 13th century. The site features houses, notably summer settlements, terraced fields, stone tracks and evidence of iron smelting. - AsNotedIn
