Lewis County

Lewis County is an administrative division in northeast Missouri that covers rolling terrain with farmland interspersed among small communities. Monticello serves as the county seat where government offices are located.

The county was established in 1833 and named after Meriwether Lewis, governor of the Louisiana Territory who led the expedition of exploration with William Clark. This connection links the region to early American westward exploration.

The county seat of Monticello sits at the heart of the region, where local life revolves around the courthouse and community gatherings that bring residents together throughout the year.

The best way to explore the region is to travel along the main roads connecting the various communities throughout the county. Monticello provides the central point for accessing services and information about the area.

The courthouse built in 1875 in Monticello remains one of the few courthouses from that decade still operating in Missouri and stands as a prominent landmark. The structure reflects the craftsmanship and design of the period.
