Monte Carlo (/ˌmɒnti ˈkɑːrloʊ/, Italian: [ˈmonte ˈkarlo]; French: Monte-Carlo [mɔ̃te kaʁlo], or colloquially Monte-Carl [mɔ̃te kaʁl]; Monégasque: Munte Carlu; lit. "Mount Charles") is officially an administrative area of the Principality of Monaco, specifically the ward of Monte Carlo/Spélugues, where the Monte Carlo Casino is located. Informally the name also refers to a larger district, the Monte Carlo Quarter (corresponding to the former municipality of Monte Carlo), which besides Monte Carlo/Spélugues also includes the wards of La Rousse/Saint Roman, Larvotto/Bas Moulins, and Saint Michel. The permanent population of the ward of Monte Carlo is about 3,500, while that of the quarter is about 15,000. Monaco has four traditional quarters. From west to east they are: Fontvieille (the newest), Monaco-Ville (the oldest), La Condamine, and Monte Carlo.
