Osage County

Osage County is an administrative division in central Missouri with a mix of forests, farmland, and river valleys along the Missouri River. The county spreads across gentle landscapes dotted with small towns and rural communities.

Osage County was established in 1841 as an independent county after separating from Gasconade County. This separation reflected the administrative growth and reorganization of Missouri during the 1800s.

The Osage people, for whom the county is named, were native to this region and left their mark on the landscape through settlements and trade routes that settlers later followed.

Most government services are located in Linn, the county seat, where you can find offices for health services, emergency management, and tax collection. Access to these services is straightforward from the town's main streets.

The county seat of Linn is known by the nickname 'the mile-long city' because it stretches in an unusually extended way along its main street. This distinctive layout makes it stand out among towns in the region.
