Construction on the Benton County Courthouse was begun in 1905 and completed in 1906.  The Architects were C.E. Bell & M.S. Detweiler of Minneapolis, MN.  The builder was George Richman & Sons, Company of Kalamazoo, MI.  The heating and plumbing contractor was J.H. Fenton of Cedar Rapids, IA.  Total cost to Benton County, including new furniture was $122,999.27.  Paul Correll, was a local merchant that donated the tower clock and bell.  The bell weighs 1500 pounds and was pitched to B flat with a rich penetrating tone.  The building is 112 feet by 77 feet of Buckeye gray sandstone and the tower stands 112 feet above the foundation.  The basement story is of Kettle River sandstone.  This building has been placed on the National Rgister of Historic Places.

Ever wonder where the flag pole in front of the Courthouse came from?  In July of 1969, the Benton County American Legion celebrated their 50th Anniversary and dedicated a new flag pole that stands in front of the Courthouse.
