Concepcion is a city in northern Paraguay and capital of the Concepción Department. It lies on the Paraguay River. Founded by a Spanish Governor, named Agustín Fernado de Pinedo, the town prospered in the early years of the 20th century, as a centre for the north of the country, exploiting the new wealth of the Gran Chaco, and a river port. The town was also a centre for the Paraguayan Civil War of 1947. The city is the seat of the Roman Catholic Diocese of Concepción en Paraguay.
