Santa Rosa was founded on 10 October 1893 by Volga Germans. It is located between the Río Gualeguay and the big valleys, near the train station of Nueva Vizcaya. In 2004, they established a museum dedicated to the preservation of the customs and traditions of the Volga Germans.
In January of 1887, nineteen families from Huck immigrated to the region of Pehuajó Norte in the southern part of Entre Ríos Province of Argentina. They had traveled through Saratov to Germany where they boarded a ship that took 28 days to reach Buenos Aires.
