Grundy County

Grundy County is an administrative division in north central Missouri with rolling hills, farmland, and the Thompson River running through it. The landscape is dominated by farms that shape both the appearance and economy of the region.

The county was established in 1841 from parts of Livingston County and named after Felix Grundy, a United States Attorney General. This formation reflected Missouri's expansion of its administrative structure during that era.

The county seat of Trenton serves as the center for local government, schools, and community services that shape daily life in the region. The town and surrounding areas reflect the farming heritage and way of life typical of rural Missouri counties.

U.S. Route 65 and Route 6 are the main transportation routes that connect the county to neighboring regions. These highways make it easy to explore the rural landscape and its communities.

Three coal mines operated in the region from 1873 to 1943 and were connected by railroad lines. This mining infrastructure played an important role in the economic development of the area.
