Chistabino is the variety of Aragonese, a Romance dialect descended from Latin, like Spanish, still spoken in the Valley of Gistau, bordering on France and formed by the River Cinqueta, in the central part of the Spanish Pyrenees (Province of Huesca). Although it is spoken mainly in the village of Gistaín (c. 240 inhabitants; c. 1400 m above sea-level, near latitude 42°35′), and is fairly well preserved by the older generations there, fluent speakers can still be found also in the nearby locality of San Juan. The other inhabited villages in the valley (Plan, Serveto, Sin and Saravillo) have suffered much greater degrees of erosion by Castilian (Standard Spanish), which has increased its influence through much improved communications, leading to the development of tourism in the area and emigration by the young in search of greater prosperity. The remaining village, Señes, has been uninhabited since 1970.
