In 1854, the decision was made to build a larger courthouse at the south end of “Silk Stocking Road”, now Main Street. From 1854 to 1908 several additions and changes were made to the courthouse. During the American Civil War, Columbiana was connected to the nearby town of Shelby by the Shelby Iron Company Railroad, which connected the Shelby Iron Works to the Alabama and Tennessee River Railroad. The Iron Works supplied iron to the C.B. Churchill and Company foundry, which moved to Columbiana in 1862 after the fall of Corinth, Mississippi. The Churchill foundry made eight and ten pound shot, eight and ten pound shells, and shells for Blakely rifles. The C.B. Churchill and Company foundry, Shelby Iron Works and the railroad were destroyed by Union forces on March 31, 1865, as part of Wilson's Raid.
