The population is 356,595 (2006), of whom a quarter live in the capital Lugo. The capital city was an ancient Celtic settlement named in honour of the god Lugh (see Lyon), later Latinised as Lucus Augusti, and which became one of the three main important Galician-Roman centres alongside Braccara Augusta and Asturica Augusta (modern Braga and Astorga respectively). The province has 67 municipalities.
The vast majority of people have a common language which is Galician. Some people, especially the older generation, are monolingual and only speak Galician. There are only a few people bilingual in Galician and Castilian of the little over 10,000 inhabitants. Even in the capital, the vitality of the Galician language in conversation is very strong.
They speak several variants of Galician in the province of Lugo. They have the characteristics of being the closest to León isoglosses and therefore also the Castilian language. So they have some grammatical and phonetic signs that are mistakenly considered influences of the Castilian or Leonese languages. However, the language of Galicia in Lugo, especially in non-coastal areas, is probably the most genuine in Galicia, due to almost no historic pressure of Castilian exercised on the rural population.
