Salamanca is a province of western Spain, in the western part of the autonomous community of Castile and León (Castilla y León). It is bordered by the provinces of Zamora, Valladolid, Ávila, and Cáceres; it is bordered on the west by Portugal. It has an area of 12,349 km ² and in 2014 had a population of 342,459 people. It is divided into 362 municipalities, 11 comarcas, 32 mancomunidades and five judicial districts. Of the 362 municipalities, more than half are villages with fewer than 300 people.HistoryThe Vettones occupied the areas of the current Spanish provinces of Salamanca and Ávila, as well as parts of Cáceres, Toledo and Zamora. They were a pre-Roman people of Celtic culture. Their numerous archaeological sites exist throughout the province, and several locality names have Vettone origin, some of which are quite important. This is the case of Salamanca (Salmantica), Ledesma (Bletisama) and Ciudad Rodrigo (Augustobriga). Vettone villages were often established on the banks of rivers or on mountains. Examples include Salamanca and Ledesma, built along the Tormes, Bermellar, El Castillo (Saldeana) Moncalvo (Hinojosa de Duero), Picon de la Mora (Picones) and Castro de Yecla la Vieja (Yecla de Yeltes) next to Huebra, Ciudad Rodrigo, Irueña (Fuenteguinaldo) and Lerilla (Zamarra) on the banks of the Agueda and Castro de Las Merchanas (Lumbrales), in a loop of the Camaces. The area between La Armuña and Salamanca marked the border between Vettones and Vaccaei, the other pre-Roman people of the province. They were situated in the northeast area of the province.
