Since opening in 1941, the Cow Palace has welcomed 50 million visitors through its doors. The Cow Palace is officially the 1-A District Agricultural Association, a State agency of the California Department of Food and Agriculture's Division of Fairs and Expositions. The Cow Palace was completed in 1941. The new arena boasted a concrete and steel roof that covered nearly six acres. The first event to be held in the new arena was the Western Classic Holstein Show in April, 1941. In November of that year, the first Grand National Rodeo was held, featuring a tribute to the late Will Rogers. The show was declared a smash hit. Cow Palace highlights include appearances by the Royal Canadian Mounted Police, Liberace, the Billy Graham Crusade (with attendance of 696,525), John F. Kennedy, Evel Knievel, the Beatles, the Rolling Stones, and Elvis Presley. In addition to these, the Cow Palace has been the host of many successful sold-out concerts.
