Hermosillo

Cathedral of the Assumption, Hermosillo, Mexico

Hermosillo, city, capital of Sonora estado (state), northwestern Mexico. It is situated in the west-central part of the state at an elevation of about 700 feet (210 metres) near the confluence of the Sonora and San Miguel rivers (which both descend from the western flank of the Sierra Madre Occidental). The Spanish colonial government founded a town in 1700 on the former site of an indigenous settlement. The town was renamed in 1828 to honour José María González de Hermosillo, a Mexican general who led an uprising against the Spanish.

Hermosillo’s economy has been increasingly oriented toward trade with the United States since the 1980s, owing in large part to an automobile-assembly plant and the growth of light-industry maquiladoras (export-oriented assembly plants) producing clothing, automobile parts, electronics, and processed foods. In addition to its industrial and administrative functions, Hermosillo is a winter resort and the site of the University of Sonora (1938). It is also a market and service centre for nearby copper mines and farmlands where cattle are raised and irrigated crops of fruit, wheat, cotton, corn (maize), and beans are grown.

Rapid population growth accompanied the city’s industrial development, and modern buildings now contrast with those of Spanish colonial design. Major highways and railroads link Hermosillo with the border cities of Mexicali, Baja California, and Nogales, Arizona, to the north and with distant Guadalajara and Mexico City to the southeast. Hermosillo has an international airport. Pop. (2010) 715,061; (2020) 855,563.
