Ansó

Ansó stands above the Veral River in a Pyrenean valley enclosed by mountains more than 2,000 metres high. In 1375 its representatives arbitrated a dispute between the neighbouring valleys of Roncal and Barétous over grazing and springs. Their ruling established the annual delivery of three cows by the people of Barétous to those of Roncal, a settlement remembered as the Tribute of the Three Cows.
