Keokuk County Courthouse

The Keokuk County Courthouse located in Sigourney, Iowa, United States, was built in 1911. It was individually listed on the National Register of Historic Places in 1981 as a part of the County Courthouses in Iowa Thematic Resource. In 1999 it was included as a contributing property in the Public Square Historic District. The courthouse is the fourth building the county has used for court functions and county administration.

Keokuk County built its first courthouse in Sigourney in 1845 for $218. The 24-by-20-foot building, which was constructed of logs, also housed the jail and served as a schoolhouse, public hall, and hotel. Lancaster became the county seat in the late 1840s and a two-story frame courthouse was built there in 1848 for $699. By the mid-1850s the county seat was back in Sigourney. A new courthouse was built in 1858 for $17,200. It was remodeled over the years until the present courthouse was begun in 1909. It was completed two years later at a cost of $150,000.
