The Union Block, located at the northwest corner of the Chariton square, had nothing to do with the Civil War. Instead, it represented a "union" between Chariton Masonic and I.O.O.F. lodges to construct a building that would house on its top floor their meeting rooms. Smith H. Mallory backed but did not own this building. He moved First National Bank into rooms on the first floor during 1882. This building stood for approximately 100 years until it was demolished and replaced by the architectural abominations that now serve banks on this corner and a block west, site of the old Bates House hotel.
