La Garcipollera
Spain
La Garcipollera (in Aragonese and officially A Garzipollera), also known as Garcipollera Valley, is a small area of the Aragonese Pyrenees, within the Jacetania, in the province of Huesca, practically coinciding with the basin of the Ijuez river, a tributary of Aragon. It is characteristic because most of its villages were depopulated during the 20th century.
