Monona County was named for a Native American work, which may mean “Peaceful Valley” or “Beautiful Valley.”
Ashton served as Monona County’s first county seat, with a log cabin serving as its courthouse.
A frame courthouse was constructed in 1858 when the county seat was moved to Onawa. Several challenges followed, but the county seat remained in Onawa.
Today’s courthouse is a Romanesque brick design with gabled roof and tower by S. E. Maxon, was completed in 1892. Additions were built in 1967 and 1973. An annex was completed in 1981 to provide facilities for court facilities and human services.
The Monona County courthouse was added to the National Register of Historic Places in 1981.
