city, Riverside county, southwestern California, U.S. Located about 45 miles (70 km) southeast of Los Angeles, Corona lies at the east end of the Santa Ana Canyon on the northeastern edge of the Santa Ana Mountains. Originally inhabited by Luiseño Indians, it became part of the Rancho La Sierra land grant. It was laid out as South Riverside when Queen Colony, a citrus growers' organization, was established (1886). In 1896 it was renamed Corona (Spanish: “Crown”) for a 3-mile (5-km) circular drive that is now around the central city and was the site of international automobile races from 1913 to 1916. Largely known for its agricultural products, it was the site of the first lemon-processing plant (1915) in the United States and subsequently developed as a citrus-processing and shipping centre. Other crops include alfalfa, sugar beets, tomatoes, and walnuts. Light manufacturing, mining, and retail are economically important. A notable local attraction is the Fender Museum of Music and the Arts (opened 2002), which provides educational programming for children. Mathews Dam to the east impounds Lake Mathews. Cleveland National Forest, Chino Hills State Park, and Glen Ivy Hot Springs are nearby. Inc. 1896. Pop. (1990) 76,095; (2000) 124,966.
