Sas is a village in the municipality of Sarroca de Bellera, in the Pallars Jussà region. The site of Sas has been documented since 887, when it is mentioned in a document from the monastery of Santa Maria de Lavaix, and is documented again in 986 and 1024. These documents speak of the place and the castle of Sas. There are no remains of the castle. In 1994 it had only one resident, but in 2005 it had 4 again. The "Font de Cantoria" spring is somewhat hidden, but right in town, but there is also a drinking water point in the middle of town.

Monesma and Cajigar are two rural cores that form one only administratively. In the village breathes a peaceful agricultural atmosphere and its stone tower stands out among the surrounding cereal fields.

Serraduy is a town belonging to the municipality of Isábena and located on the banks of the homonymous river. Some of the houses were built on the same rock, since the terrain is quite steep. The town is divided in two by the river and connected by a beautiful medieval bridge. A few meters from the village, on the road, the Casa Peix hotel-restaurant has a terrace with beautiful views of the river and the Sis mountain range.
