About Us

Knoxville is located in south-central Iowa, some 25 miles southeast of Des Moines. The area was originally inhabited by Native Americans of the Sac and Fox tribes. At that time, prairie grass covered the countryside at heights of 8 to 10 feet. In 1835, Dragoons first explored the Des Moines River valley through this area. In 1842, the Sac and Fox Indians signed a treaty to sell lands in central Iowa to the new settlers known as the New Purchase of 1842. By 1843, settlers began moving here. The first Marion County Courthouse was erected three years later.

Knoxville was founded in 1845 when Joseph Robinson and James Montgomery, Commissioners from Scott and Wapello County, selected the site for Knoxville and designated it as the county seat. They named Knoxville in honor of General Henry Knox, hero of the Revolutionary War. The City’s main streets are named after Robinson and Montgomery.

County surveyor Isaac B. Powers platted part of the town in September 1845, shortly after it was located. Clairborne Hall laid out the remainder of the town in the winter of 1846-47. Additional surveys were made in December 1849 and September 1852.

The first sale of lots on October 21, 1845 saw the best sites in town go for $15 to $65. The first survey made the streets 80 feet wide, alleys 10 feet wide, and lots 120’ x 60’, but the third survey changed the width of the streets to 50 feet, and made the blocks 265’ x 240’.

The first Marion County courthouse was built on a lot owned by L.C. Corny. Contractor Lewis M. Pearch started work on May 29, 1846 at a cost of approximately $80,000.
