Village
Ansó is a village in the western Pyrenees of Huesca, in the comarca of La Jacetania, on the middle course of the Veral river valley. It has 409 inhabitants (INE 2025) and has belonged, since 2015, to the association Los Pueblos Más Bonitos de España, whose accreditation recognises its well-preserved historic centre and its famous traditional costume. Its municipal area, bordering France, is bounded to the east by Valle de Hecho and to the west by Navarre, and extends into the Parque Natural de los Valles Occidentales and the Paisaje Protegido de las Fozes de Fago y Biniés. Upstream on the Veral lies the enclave of Zuriza, with a campsite housed in an imposing 19th-century building that served as barracks for the Carabineros corps until its dissolution in the 1940s.
Monument
The Museum of the Ansó Costume was inaugurated in 2011, the same year in which the Festival of the Ansó Costume was declared a Fiesta de Interés Turístico Nacional (a festival of national tourist interest), and it occupies the former hermitage of Santa Bárbara, in Ansó (La Jacetania, Huesca). Before that date, the same building already housed a small parish museum that, since 1970, had displayed local ethnographic heritage during the festivals. The collection traces chronologically the stages and transitions of life in Ansó through its clothing: work and festive dress differentiated by sex, children's outfits for christening, confirmation and everyday use, wedding attire, and the dress of the confraternity and its mayordomos, besides traditional jewellery of the comarca.

Nature
The Valle de Ansó is a Pyrenean valley situated at the westernmost point of the Huesca Jacetania, formed by two villages, Ansó and Fago. It borders the Roncal valley, in Navarre, to the west, French Béarn to the north, Valle de Hecho to the east and the Canal de Berdún to the south; it covers 25,850 hectares and is included in the Parque Natural de los Valles Occidentales. Its resources are managed jointly between Fago, with a fifth share, and Ansó, with the remaining four fifths, through the Mancomunidad Forestal Ansó-Fago. Access is via Biniés; the valley widens at the village of Ansó, narrows at Zuriza and opens out again in the Zuriza valley to the north, divided into two small glacial valleys. The Veral river is its main axis.

Traditional dress of the valleys of Ansó and Hecho, one of the most singular folk costumes of the Aragonese Pyrenees.

Food and drink
The ansotana is a native Aragonese sheep breed, found mainly in the province of Huesca, in the valleys of Hecho and Ansó, from which it takes its name; the Catálogo Oficial de Razas de Ganado de España lists it among the breeds at risk of extinction. It belongs to the entrefino stock of the Pyrenees and has traditionally been closely linked to the rasa aragonesa sheep; it is a very hardy animal with a semi-closed fleece, in which both sexes can grow horns, though these are more common in males. It is raised mainly for meat, and the ansotana is one of the breeds covered by the protected geographical indication Ternasco de Aragón, which requires lambs under ninety days old raised on their mother's milk and carcasses of between eight and thirteen kilos.
