Its cultural capital is Tamarite de Litera, its administrative capital is Binefar and it borders the comarques of Ribagorza, Somontano de Barbastro, Cinca Medio, Bajo Cinca in Aragon and Noguera and Segrià in Catalonia.
Somontano de Barbastro (Aragonese: Semontano de Balbastro) is a comarca in Province of Huesca, Aragon, Spain.
Somontano borders the comarcas of Sobrarbe and Alto Gállego to the north, Ribagorza and La Litera to the east, Cinca Medio to the southwest, the Monegros desert to the south and Hoya de Huesca to the west.
Ponent, also known as the Lleida region following the vegueries law, is the westernmost of the eight regions (vegueries) defined by the Regional Plan of Catalonia. It has an area of 5,586 km, and 365,289 inhabitants as of 2022.
The region includes the comarques of Segrià, Garrigues, Noguera, Pla d'Urgell, Segarra and Urgell. Within Catalonia, it borders to the north with Alt Pirineu, to the east with Central Catalonia, Penedès and Camp de Tarragona, and to the south with Terres de l'Ebre. Outside of administrative terms, the name is sometimes used including the Aragonese comarques of Baix Cinca and La Llitera, which are part of the Catalan-speaking territory in Aragon known as Franja de Ponent.
Ribagorza (Spanish: [riβaˈɣoɾθa], Aragonese: [ɾiβaˈɣoɾθa]) or Ribagorça (Western Catalan: [riβaˈɣɔɾsa]; French: Ribagorce) is a comarca (administrative subdivision) in Aragon, Spain, situated in the north-east of the province of Huesca. It borders the French département of the Haute-Garonne to the north and Catalonia (the comarques of Val d'Aran, Alta Ribagorça, Pallars Jussà, and Noguera) to the east. Within Aragon its neighboring comarcas are Sobrarbe, Somontano de Barbastro, and La Litera. It roughly corresponds to the Aragonese part of the medieval County of Ribagorza. The administrative capital of Ribagorza is Graus, although the historical capital of the county was at Benabarre.
The Ribagorçan dialect is a transitional Aragonese–Catalan dialect spoken in the western part of the comarca. Municipalities in the eastern part, bordering Catalonia, are part of La Franja, a geolinguistic area, where the local language is a variety of Catalan. However, Aragonese and Catalan form a dialect continuum here and the geographical limit of both languages cannot be drawn in a clear-cut manner.
