Rivadavia is a department of the province of San Juan (Argentina). Located in the central southern part of Argentina, in the northeast section of the Valle del Tulum The city of San Juan is located in the west of this region, which is part of the conurbation, Grand San Juan. It is the capital city of the department of the same name, and is the government seat. It has various municipal edifices, including the police headquarters, and an important hospital, Marcial Quiroga.
The municipal law of December 7, 1869, divided the province into 18 departments. One covering the current areas Marquisate (current district department), Zonda and Ullum. These zones cover a substantial area, which responded to the low population in the area.In 1890, the Echezarreta brothers, Nicolas and Agustin, established a central population in the department and therefore presented a draft to the village head in Marquisate, since both brothers were planting vineyards in the Marquesado area and wanted to attract potential employees.
The project, which defined the layout of the village on a main road with an area of 60 hectares, was approved. The sale of plots was more than successful, and a year later the town had become a tourist attraction for the province. The population began to grow by leaps and bounds. The brothers Echezarreta also donated their vast fields properties to institutions such as Bethany House, an establishment where retreats are held at present, and partly to Regiment Mountain Infantry number 22.
At the beginning of the century, under the governance of Colonel Carlos Sarmiento, the town was legally named Rivadavia on August 25, 1908. In 1909, the executive branch authorized the creation of a villa in the department for the seat of municipal authorities, expropriating the required land. In 1928 a new law was enacted by the Municipal Regime, which included Rivadavia within the department capital. On March 7, 1935, during Juan Maurín's term of office, new legislation on the subject reappeared independently.
On September 19, 1942, Rivadavia became one of the 19 department of the province, with the village of the same name and with the current limits
