Asunción (UK: , US: , Spanish: [asunˈsjon]) is the capital and largest city of Paraguay. The city is located on the left bank of the Paraguay River, almost at the confluence of this river with the River Pilcomayo, on the South American continent.
The Paraguay River and the Bay of Asunción in the northwest separate the city from the Occidental Region of Paraguay and Argentina in the south part of the city. The rest of the city is surrounded by the Central Department. The city is an autonomous capital district, not a part of any department. The metropolitan area, called Gran Asunción, includes the cities of San Lorenzo, Fernando de la Mora, Lambaré, Luque, Mariano Roque Alonso, Ñemby, San Antonio, Limpio, Capiatá and Villa Elisa, which are part of the Central Department. The Asunción metropolitan area has around two million inhabitants. The Municipality of Asunción is listed on the Asunción Stock Exchange, as BVPASA: MUA. Asunción is one of the oldest cities in South America and the longest continually inhabited area in the Río de la Plata Basin; for this reason it is known as "the Mother of Cities". From Asunción the colonial expeditions departed to found other cities, including the second foundation of Buenos Aires and other important cities such as Villarrica, Corrientes, Santa Fe and Santa Cruz de la Sierra.
