The Columbia County Courthouse was built in 1905 at a cost of under $60,000, which was funded by a 2-mill tax levy that was passed in 1903. The Courthouse was designed by W.S. Hull in the 2nd Renaissance Revival Styling, this was done in 1905. The Courthouse features include Corinthian pilaster separating the windows on the exterior of the 2nd level. While on the 1st level a projecting Greek temple portico with recessed entries under round arches and fluted Corinthian Columns.
The Courthouse was placed on the National Register of Historic Places in 1978.
The current courthouse was not the 1st one built. In 1852, almost immediately after Columbia County was organized, a temporary log courthouse was built on the south side of the square. Then, in 1856, a second courthouse was built on the same site which the current courthouse sits. The 3rd , and present, courthouse was built in 1905, at a cost of under $60,000, which was funded by a 2-mill tax levy that was passed in 1903.
