Johnson County was named for Richard Mentor Johnson, the ninth vice president of the United States.
The first courthouse of Johnson County was a two-story log building built in Napoleon, Iowa in the year 1838.
The county seat moved to Iowa City in 1840, and a two-story brick courthouse was completed in 1842. It was destroyed by fire in 1856.
Johnson County’s third courthouse was a brick Gothic Revival structure built in 1857, and was condemned in 1899.
The current courthouse, a Richardsonian Romanesque structure designed by A. William Rush, was built beginning in 1899. Constructed by James Rowson and Son, the rough-cut stone building features turrets and stone carvings above the arched entrance. The Johnson County courthouse was added to the National Register of Historic Places in 1975.
