Borau
Borau has the rank of "town", which announces the relevance of its past as a population nucleus and a remarkable agricultural and farming center in this area. Its built at 1.008 meters of altitude and it is crossed by the river Lubierre, a tributary of the river Aragón. At the entrance of the village the old school building constructed in 1928 rises up, a beautiful and unusual exponent of civil architecture in the Pyrenees. Its narrow streets, paved and full of details, its 16th century church, watching over the city from its standpoint, the slate and flagstone roofs, and chimneys typical of the Pyrenees make Borau be one of the best preserved places in the area.

Very near Borau there is San Adrián de Sasabe (10th c.), which was one of the most important monasteries during the High Middle Ages, although today only a church remains, surrounded by the gullies of Cáncil and Lupán.

The hypotheses about the origin of Sasabe are diverse, but the most widespread explanation is the one afforded by Father Ramón of Huesca in the 19th century. According to it, St Adrian was a Visigothic monastery in which the bishops of Huesca took refuge in the escape from the Arabic invasion. They took with the Holy Grail, which explains the historic significance that this monastery holds for Christianity. In fact, it seems clear now that the monastery was the seat for the bishops of Aragón from the 10th century until the seat of Jaca was created in 1077.

San Adrián de Sasabe consists of only one rectagular nave with presbytery and a semicircular apse covered by a quarter sphere vault. The inside is extremely severe. The only ornament on the walls is a flying imposta (the top brick course upholding the arch). In the outside, architectonic details are more abundant and thus we can see a simple ajedrezado (chessboard pattern) which frames the arch of the southern doorway. The western facade shows much influence from the Romanesque art of Jaca, and some characteristics that remind us of the nearby chapel of Santa María of Iguacel.
