Corona, originally named South Riverside, was founded at the height of the Southern California citrus boom in 1886, and is situated at the upper end of the Santa Ana River Canyon, a significant pass through the Santa Ana Mountains. The town of Corona was once the "Lemon Capital of the World". A museum there presents the lemon's former role in the local economy. The city derived its name (and its nickname, "The Circle City") from the unique layout of its streets, with a standard grid enclosed by the circular Grand Boulevard, 2.75 miles (4.43 kilometers) in circumference. The street layout was designed by Hiram Clay Kellogg, a civil engineer from Anaheim who was an influential figure in the early development of Orange County.
