Founded in 1864 on Granite Creek, Prescott was an early source of placer gold and a former territorial capital of Arizona. It became a center for ranching, mining, and health, especially asthma relief. Located here on the site of old Fort Whipple is Whipple Veterans Hospital. Prescott is the seat of the First Governor's Mansion and Arizona Pioneer's Home. Frontier Days, the oldest rodeo in the west, began here.
