Asunción is one of the oldest cities in South America and the longest continually inhabited area in the River Plate Basin; for this reason that it is known as "Mother of Cities". It was from here that the colonial expeditions departed to found other cities, including the second foundation of Buenos Aires and of other important cities such as Villarrica, Corrientes, Santa Fe and Santa Cruz de la Sierra.
Asunción city sits on the left bank of the Paraguay River, almost at the confluence of this river with the River Pilcomayo. 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.
