Doniphan County, Kansas
Doniphan County occupies the northeastern corner of Kansas, with the Missouri River forming its eastern border. The county is home to about 7,500 residents and features a landscape of rolling hills and river valleys, offering a different setting from the flatter plains found across much of Kansas.
Troy, the county seat, may be a small community, but it has a rich local heritage with strong connections to the early history and development of Kansas statehood.
Visitors can explore historic sites such as the Iowa, Sac, and Fox Mission, which offers insight into the area’s early Native American history and cultural heritage. The county’s proximity to the Missouri River also contributes to its natural beauty and historical significance.
