Lady Justice

The building, completed in 1886, was the second courthouse in the county. The first courthouse in the county, a 20-by-24 foot one-story stone building, was built in 1857. It served as the location for the trial of 392 Dakota Indians after the Sioux Uprising. Thirty-eight Dakota were simultaneously hanged in December 1862.[2]

By the late 1800s, the county commissioners felt that the previous buildings were a "disgrace and gave strangers that we were behind the times. That the county was either poverty stricken or greatly lacking in enterprise."[2] The new building combined a Second Empire roof and dome with Italianate features. The stone was provided by a local quarry, with various techniques giving it both rusticated and ashlar surfaces. The copper-sheathed dome is capped with a statue of Lady Justice.[3]
