Originally named
Nicolás Avellaneda, it was founded on July 9, 1879, by General
Conrado Villegas. After a flood, the inhabitants moved to a place known as
Pampa de los Molinos. They would stay there until March 18, 1882, when the settlement was moved to its current location. The town acquired special importance during the
Conquest of the Desert, when the border between the white man and the Native Americans was pushed south the shore of the
Río Negro River. In 1883, a post office was installed in the town.
Salesians arrived in 1890. The Provincial School #10 was created in 1904, and in 1917 the Library.
Irish Argentine writer
Rodolfo Walsh was born in the town in 1927. In the 1900s a group of
Welsh settlers who were considering leaving Argentina were granted land in Choele Choel. Choele Choel is home to a sizable
Russian community (some of them
Old Believers). Besides the European
immigrant communities common to most of Argentina, the town received refugees from
Laos in the 1970s. ==Climate==
