Ures is one of the oldest cities of the state of Sonora. It was founded as a mission by the Jesuit missionary Francisco París, and was known as San Miguel de Ures until 1665. In 1823 Ures became the capital of Sonora, but was replaced the following year when Sonora was merged into Occidente State.
At the end of 1838, Ures became a city; and was the capital of Sonora from 1838 to 1842, and again from 1847 to 1879. Afterwards, it became the seat of a district, until these were abolished in 1917.
In this region there were some notable events, as the Apache insurrection, when Geronimo took refuge in the mountains of this region when generals Crook and Miles fought him in Arizona. The most notable Apache raids were in 1870, when the priest Echevería was killed in the town, and in 1882, when the distinguished scholar Leocadio Salcedo was killed at the La Noria ranch. Residents of the region also had problems with Yaqui uprisings and insurrections of the late 19th and early 20th centuries. On September 5, 1998, the state legislature gave it the title of Heroic City, in recognition of its defense by liberals against imperialists in the French Intervention. 
In Ures you can visit “La Plaza de Armas(La Plaza de Zaragoza)” with its four 18th century bronze sculptures, San Miguel Mission and the church bearing the same name with its legendary mesquite stairway. In addition, you will see the majestic arch commemorating the Independence and the house where General Pesqueira used to live, The Folkloric Museum, and the old Flour Mill.
