Piatt County, named for James A. Piatt, Sr., was established January 27, 1841, from territory taken from Macon County. The County is 34 miles long, containing 279,680 acres. Approximately 91% of this area is cropland, 3% pasture, 1% woodland and 5% other (municipalities, waterways, highways). Elevations vary from 650 to 800 feet above sea level.

The County Seat is Monticello. On July 1, 1837, James A. Piatt filed a plat of Monticello in the old Courthouse in Decatur. On July 4, 1837, a barbecue was held and lots were sold in the city named for the Virginia home of Thomas Jefferson.
