First National Bank (Ottumwa, Iowa)
First National Bank is a historic building located in downtown Ottumwa, Iowa, United States. It is significant for its architectural design and its use of terra cotta for the exterior, the only bank in town so clad. Chicago architect H. H. Stoddard designed the building in the Neoclassical style. It was built by the Blackhawk Construction Company in 1915. The building replaced the original 1868 bank building rebuilt after a fire in 1881, also at this location. The two-story structure features a pediment and two columns flanking the main entrance. The exterior is composed  entirely of cream colored terra cotta. Dentil ornamentation is found across the top of the building. Initially the building was a single story with ceilings, but it was altered to its present form in 1956. The glass wall of the main facade was also added at that time. The building was listed on the National Register of Historic Places in 1995.
