About Formosa
Formosa (Spanish pronunciation: [foɾˈmosa]) is the capital city of the Argentine province of Formosa, on the banks of the Paraguay River, opposite the Paraguayan town of Alberdi, about 1,200 km (746 mi) north from Buenos Aires, on National Route 11. The city has a population of about 234,000 per the 2010 census [INDEC].
Formosa is the hub of the provincial industry, that processes the product of its natural resources. The port that serves Paraguay towards the Paraná River is the main transport means for the provincial production.
Notable sights of the city include the Nuestra Señora del Carmen Cathedral, the Government House, the Torelli Botanic Forest Garden, the Provincial History Museum (Museo Histórico Provincial), the Estadio Centenario ("Centenary Stadium") football stadium, the Guaicole fauna reserve, the shore of the Paraguay River, the Isla de Oro Island, and the Central Square named after José de San Martín.

Formosa in Depth
History
The lands were initially inhabited by the Toba and Wichí (Mataco) indigenous peoples. On April 8, 1879 Commander Luis Jorge Fontana founded the settlement that would become the capital of the National Territory of Chaco from 1884 to June 15, 1955, when it gained the status of province. The Formosa campus of the National University of the Northeast was established as the National University of Formosa in 1988.
The name of the city (and the province) comes from the archaic Spanish word fermosa (currently hermosa) meaning "beautiful". The name Vuelta Fermosa or Vuelta la Formosa was used by Spanish sailors in the 16th century to describe the area where the Paraguay River makes a turn, right in front of the actual city. These sailors were searching for the legendary Sierra de la Plata.
