Biohazard and Crime Scene Remediation in Monticello, MO

Monticello is a rural village and the county seat of Lewis County, Missouri, standing on the east bluffs of the North Fabius River.

With just 104 residents at the 2020 census, Monticello is the smallest county seat in the entire state of Missouri.

The village is named in honor of Monticello, President Thomas Jefferson's estate in Virginia.

After Lewis County was established on January 2, 1833, two commissioners passed over the established river villages of Tully and Canton and chose a site near the county's geographic center for the seat; settler Andrew P. Williams donated sixty acres, and the town was laid out in the fall of 1833 and surveyed in 1834.

Monticello's first courthouse was a single-story log structure completed by June 1834, replaced by a more substantial two-story brick courthouse in 1839.

The Lewis County Courthouse in Monticello was listed on the National Register of Historic Places in 2005.

Monticello and the surrounding area leaned Confederate during the Civil War, and one of its most notable citizens was Martin E. Green, who became a Confederate brigadier general.

The village covers only 0.26 square miles, and the 2010 census counted 98 people living in 42 households.

Monticello is part of the Quincy, Illinois–Missouri Micropolitan Statistical Area, and although its population was estimated at about 350 in the late 1890s, the farm crisis of the 1980s and out-migration shrank it to 126 residents by the 2000 census.
