It is a village of the province of Huesca, located in the somontano ,(under mountains) of the Huesca Hole region. They are about 320 inhabitantns. Altitude: 560 meters on the sea level. It is from Huesca 29 kilometers. Gentile: casbasino..
    The Huesca somontano ascends on the basin of the Alcanadre river. We must follow the highway of Barbastro, until Angúés village, from where will be taken the deviation for Casbas, in the left hand. In a little time, the traveller will meet an urban nucleus of singular interest, for its medieval sketch, of the which highlights the group formed for the Santa María monastery (Cistercian), much more acquaintance popularly as monastery of Casbas. It took the surname of the little town from 1857, in which it was named Casbas de Huesca; without doubt to differentiate of its namesake of Casbas de Jaca, that was depopulated.
     The little town appears when overflowing the deviation to Junzano, on the right hand. Although the traveller would arrive thinking about the monastery, that accumulates great part of the history and the art of the place, he should not give to wander through the streets of long path, with its picturesque corners and its full nooks of charm. The ashlar and the stone walls are present in almost all houses, many with old gates of arch formed by an exact semicircle, of the XVIII century. It is an extraordinary sample of popular architecture, in general well kept.
    Casbas means "ewe earth", according to the Jesús Conte Oliveros historian and possibly it was so at past times, when the pastureland is extended on the evenness, between the little town and the river. Jesús Pejón, born casbasino, contributed data for the first history of the village:
     -The three burials of the "callizo" of Marquínez (now it's said Marquiz) are from the Bascués time. The water was of wells; those of Zamora has a related legend to the Nunilo and Alodia female saints, born in Adahuesca. The running track was the street of saint Julian, street of the Horno until the old road. The remains of the cemetery, in saint Julian of Aflor (in other times it went named Azlor), indicate that the town was not very big-. It is from March 5, 1173 when Casbas begins to transform in a really important center for the whole region, with a decisive influence in all. It had passed the reconquest. Casbas had been conquered for the count of Urgel, who gave his rights to his daughter Lady Oria who arranged the foundation of the monastery..
     According to Durán Gudiol and Ubieto Arteta, remains constancy in the "Diplomatic collection of the cathedral of Huesca" and in "Documents of Casbas" that went on 26th February 1172 when Esteban, bishop of Huesca, conceded a licentiate to Aurea, countess of Pallás, for building a monastery in Casbas. and on 5th March 1173 , Arnaldo de Pallás recognized to the monastery the property on the churches of Casbas and other. The already mentioned Esteban bishop gave those of Arnellas and Peralta also, in 1182. And on 19th August 1295, the king Jaime Ist of Aragon exempted to the mentioned monastery of the tax of coin and other in all your places.
      The place, because, went dominion of abbey and so it figured still in 1785. In 1610 , Juan Bautista Labaña wrote of the place: "the monastery is big, the church is small, but of good form for that time... It makes little time that were some nuns; it has been reformed, and those who enter again are observants, of those who had twelve; and of the cloistered nuns, ten, that are kept in their freedom of can go out, as they do it ".
      At this point, good it will be to remember that the monastery, for being not of confinement, formed an all with the own village and that the cloistered began with the council of Trent. The monastery was builded in agreement with the Cistercian prevailing model in the time, to judge for the remains that there are kept of the original structure, just as the walls, the tribute tower, the abattial house, the cloister, the capitular hall and the monastic church.

      It then passed from the 12th century to the 15th. and also to the 16th and 17th century. as in different times were made enlargement or modification works of part of the monastery. The major renovations were made between 1652 and 1656 years during the abaciado (abbacy) of Luisa de Laporta.
      Through the large fortified tower you access to two courtyards. One of them takes directly to the cloister, after going through a gantry of the XVI century. The cloister of four corridors with lobed arcs, is from the XV century, the capitular hall is later, of the following century, to judge by the tombstones that it shines. The Romanesque church consists of nave and crossing with three apses. Meanwhile that the crossing is covered with octogonal dome, the nave makes it with barrel vault supported by transverse arches. The cover is adorned with eleven round arches in gradation, and the tympanum is decorated with the corresponding chrismon.
      Great loss represented for the monastery the war of 1936, with the disappearance of valuable works and furniture, between those highlights the chairs of the chorus, carved in 1506. by the Juan Bierto sculptor, of Saragossa. They are kept, notwithstanding, two tables of the XVI century in the high altar and a predella of paintings representing a story of the XV century.
      The parochial church of saint Nicholas was built for the José Soft architect, from Huesca, in the XVIII century, on the ancestral site of the previous church and ancient cemetery. It has plant of latin cross, with three naves, the central covered with vault of lunettes and on the both sides, of height minor, with circular vaults on pechinas. The crossing is covered with dome, on pechinas also. The tower forms part the main facade, in which is opened the door, of three bodies.
      Casbas, in other times, had for Saint Patron to San Juan Bautista; at present is saint Nicolas de Bail, and the patronal feasts are celebrated from December 6 to 9.



      There is, moreover, two hermitages, dedicated respectively, to San José and to Nuestra Señora de Bascués. The first consists of a nave covered with vault of lunettes and major chapel with octogonal dome, meanwhile that in the lateral sides are opened other chapels like a crossing. The second is Romanesque of the XII century, although was enlarged afterwards, and has also a single nave with semicircular apse.
      Casbas de Huesca formed town hall with the mountain of Bascués, in 1834. In 1960-1970 were united to it, Junzano. Labata and Sieso de Huesca; and in 1970-1980, Panzano. Its heraldic arms consist in a quartered shield, with the quarters first and fourth in golden, with three sashes of gules, and second and third of silver, with star of gules of eight tips, and the latin legend "Ave gratia plena", in sabre lyrics, on a bordure of silver.
      In one of the entrances of the little town, there is a flourishing and modern urbanization, with many single family houses and garden areas, whose prosperous future seems contained for the relentless crisis in the construction and in the general economy of the moment. Of any mode, resuts a clear exponent of the attractive residential that the Casbas village practices.
