The United States National Bank Building in downtown Portland, Oregon was designed by A. E. Doyle in a Roman classical style, and is listed on the National Register of Historic Places. The four-story building's first section, facing Sixth Avenue, was completed and opened in 1917. The building features a four-story Corinthian colonnade at its eastern end (originally the principal façade) and makes extensive use of glazed terracotta. The interior is also decorated extensively with highly textured materials.
