The oldest antecedent of this town is the San Pedro ranch, on its outskirts, properties of Justo José de Urquiza and his descendants for more than a century and a half. Here, the plot that culminated in the murder of Justo José de Urquiza, led by Sergeant Major Simón Luengo and Nicomedes Coronel, butler of the caudillo, took place.
After Urquiza's death, the properties was inherited by his daughter Justa, married to General Luis María Campos. The main house of San Pedro dates back to 1872, although the current Tudor residences was built on the original building in 1928 with the addition of splendid furniture.
