The town was founded in 1504 by Diego Velázquez, who later went to conquest the island of Cuba; the Spanish governor of the Hispaniola island at that time was Nicolás de Ovando. The town was in the original region of Azua, where there was a Taíno town and Pedro Gallego had a farm. This place is called now "Pueblo Viejo" (in English, "Old Town"), at about 8 km to the soutwest of the modern city.
