Ciudad Rodrigo (Spanish pronunciation: [θi̯uˈðað roˈðɾiɣo]) is a small cathedral city in the province of Salamanca, in western Spain, with a population of about 14,000. It is the seat of a judicial district as well. The site of Ciudad Rodrigo, perched atop a rocky rise on the right bank of the River Águeda, has been occupied since the Neolithic Age. Known also as Mirobriga by those who wish to associate the city with an ancient Celtic village in the outskirts of the modern city.
