Basel (/ˈbɑːzəl/ or /ˈbɑːl/; or less often used Basle; German: Basel pronounced [ˈbaːzəl]; French: Bâle [bɑl]; Italian: Basilea [baziˈlɛːa]; Romansh: Basilea [baziˈlɛːa]) is Switzerland’s third most populous city (behind Zürich and Geneva) with about 195,000 inhabitants. Located where the Swiss, French and German borders meet, Basel also has suburbs in France and Germany. In 2011, the Basel agglomeration was the third largest in Switzerland with a population of 500,600 in 74 municipalities in Switzerland and an additional 53 in neighboring countries (municipal count as of 2000). The tri-national Basel metropolitan area has around 830,000 inhabitants in 226 municipalities. Located in northwest Switzerland on the river Rhine, Basel functions as a major industrial centre for the chemical and pharmaceutical industry. The Basel region, culturally extending into German Baden-Württemberg and French Alsace, reflects the heritage of its three states in the modern Latin name: “Regio TriRhena”. It has the oldest university of the Swiss Confederation (1460). The official language of Basel is (the Swiss variety of Standard) German, but the main spoken language is the local variant of the Alemannic Swiss German dialect.
