Fontana, city, San Bernardino county, southwestern California, U.S. Lying just west of the city of San Bernardino, the site was once part of the Rancho San Bernardino land grant (1842). The community, then known as Rosena, was developed in 1903 after it was bought by Fontana Development Company. It was renamed Fontana (Italian: “Fountain”) in 1913 by A.B. Miller, who promoted the city’s growth as a poultry, hog, and citrus center. The U.S. Rabbit Experimental Station, the only facility in the country devoted to research on the breeding and raising of rabbits, was established there in 1928 and operated until 1965. In 1942 Fontana became the location for a large integrated steel mill. Other manufacturing plants followed, and Fontana’s basic economy was transformed from agricultural to industrial. Steel production declined in the late 20th century. The Fontana Historical Museum, located in a farmhouse built in the first part of the 20th century, depicts early life in the city. San Bernardino National Forest is north of the city. Inc. city, 1952. Pop. (2010) 196,069; (2020) 208,393.

San Bernardino, central city of the San Bernardino–RiversideOntario metropolitan complex, seat (1853) of San Bernardino county, southern California, U.S. Located east of Los Angeles, the city lies at the base of the San Bernardino Mountains. It was the site of a Spanish mission (1810) named for St. Bernardino of Siena. The mission was closed in 1834, and the land was later sold to Mormons, who established a fort and laid out a town in 1852. The discovery of gold nearby in 1862 brought an influx of settlers. San Bernardino developed as a trade centre chiefly for the surrounding citrus groves and vineyards. Aerospace and electronic industries, Santa Fe Railway shops, and other industries are now the economic mainstays. A community college was established in 1926 and California State University at San Bernardino in 1960. The city is headquarters for San Bernardino National Forest and the distribution point for the Lake Arrowhead resort area (named for an arrowhead-shaped rock formation in the San Bernardino Mountains). Popular local events include the National Orange Show (March) and the Route 66 Rendezvous, a classic-car show. Angeles National Forest is nearby. Inc. city, 1854. Pop. (2010) 209,924; Riverside–San Bernardino–Ontario Metro Area, 4,224,851; (2020) 222,101; Riverside–San Bernardino–Ontario Metro Area, 4,599,839.
