Castile-Leon (Spanish: Castilla y León) is an autonomous region of Spain.
La Alberca is worth a visit. It is historical town with a current population of about 1000. Only residents are allowed to have vehiles in the historical centre. In the off season, it can be a quiet, sleepy location. Besides being very beautiful, the town is known for the production of ham and other pork products.
Castilla y León is an autonomous community of Spain, the country's largest — in fact, it is the largest subnational political division in the European Union. It is formed by the union of two ancient kingdoms: Old Castile (Burgos, Palencia, Valladolid, Ávila, Segovia y Soria) and the Kingdom of León (Salamanca, Zamora y León), which were separated and reunited several times in the Middle Ages.
Spanish is the main language, everybody in Castile-Leon speak Spanish, but in the provinces of León, Zamora and Salamanca, Leonese is also spoken by a little minority. In Treviño (Burgos province) Basque is still preserved.
