Piatt County Facts

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.
