Knox County Courthouse

Image of the Knox County courthouseThe Knox County Courthouse was designed by architect Daniel Clark and built in 1890 at a cost of $37,000. Located at 111 East High St. in the county seat of Mount Vernon, the building is still in use and today houses the Knox County Court of Common Pleas and its probate and juvenile divisions.

The courthouse features Greek Revival style architecture and is made of brick. The building also features two spiral stone stairways and two massive sandstone pillars.  In 1890, the large courtroom on the second floor was divided to allow for more office space, the roof was completely rebuilt, and a taller, more ornate metal cupola was added. The Knox County Courthouse also features masonry groined arch vaulting, which is very unique for a courthouse. 

Knox County is named after Henry Knox, an American bookseller from Boston who became the chief artillery officer of the Continental Army during the Revolutionary War and later the nation’s first secretary of war. The courthouse was placed on the National Register of Historic Places in 1973.
