History
Monona County was formed in 1851. It was perhaps named for the Indian word meaning "beautiful valley."
When Ashton (originally called Bloomfield ) was named the county seat in the fall of 1854, a log house served as the first courthouse. Ashton remained the county seat for only four years. On April 5, 1858, Onawa was voted the permanent seat of the county.
The first Monona County Courthouse was completed in 1858.
