History

San José de Jáchal was founded on 25 June 1751 by the field master Juan de Echegaray, by the order of the Board of Populations of the Kingdom of Chile. That same month, through an interesting ceremony, the Villa de San José de Jáchal, forty leagues north of San Juan de la Frontera, was born to civilian and political life.
