The Clinton County Courthouse is located at 53 East Main Street in Wilmington, Ohio.

A pitched roof rested on a red brick cornice with two chimneys to either side and a central cupola.

Bids began to be accepted for the construction with the masonry work awarded to John Bush, and the plastering contract going to Thomas & Alfred Shockley and William & Joshua Noble.

The rectangular structure had a central entrance framed by four Doric columns supporting an unadorned pediment.

During a competition, the design was awarded to plans submitted by the architectural firm of Weber, Werner & Adkins with a budget of $300,000 allotted to the project.
