Rio Negro | Argentina

Viedma serves as the administrative capital of the Río Negro Province and the oldest European settlement in Patagonia. It is situated on the southern bank of the Negro River, approximately 30 km from the Atlantic Ocean, directly opposite the city of Carmen de Patagones.

Historical Timeline

Founded on April 22, 1779, by Francisco de Viedma y Narváez as a fortress (Fuerte del Carmen). Originally, Viedma and Carmen de Patagones were a single settlement; they were administratively split in 1878 with the river serving as the boundary. In 1986, President Raúl Alfonsín famously proposed moving the Federal Capital of Argentina to Viedma, a project that led to significant local infrastructure planning before being indefinitely postponed due to economic constraints.

Demographics & Population

The metropolitan population (Viedma–Carmen de Patagones) is approximately 85,000 as of 2026. The demographic is primarily administrative and agricultural, with a significant portion of the workforce employed by the provincial government. Residents are known as Viedmenses.

Average internet speed is 70 Mbps. 5G is available in the historic core and the provincial government area. The "Blue Dollar" and Mercado Pago are standard. As a provincial capital, the city has a high density of bank branches and public administration offices.

Cool semi-arid climate. Temperatures range from 2°C to 14°C in winter and 16°C to 30°C in summer. The city is notoriously windy throughout the year, with average speeds of 25 km/h. Air quality is excellent, influenced by the Atlantic breeze and the lack of heavy industrial pollution.

Facts & Legends

A prominent legend involves the "Cave of the Tigers" (Cueva de los Tigres) in the river cliffs, said to have sheltered early explorers and bandits. A verified historical oddity is that Viedma is the only city in Argentina to have technically been a "Federal District" for a few years during the 1980s capital relocation project. Another fact: the Negro River is the only one in Patagonia that does not originate in a lake, but rather from the confluence of the Limay and Neuquén rivers.
