The Columbia County Courthouse is located at Court Square in the heart of Magnolia, the county seat of Columbia County, Arkansas. The two-story brick and stone structure was designed W. W. Hall and built in 1905. It features Renaissance Revival styling, with Corinthian pilasters separating the windows on the second level and a projecting Greek temple portico with recessed entries under round arches on the first level, and fluted Corinthian columns on the second.
African-American man, Jordan Jameson was lynched on November 11, 1919, in the town square right in the front of the Columbia County Courthouse. A large white mob seized Jameson after he allegedly shot the local sheriff. They tied him to a stake and burned him alive meters from the building.
The building was listed on the National Register of Historic Places in 1978.
