The Spalding Building, formerly the Oregon Bank Building, is a historic office building in downtown Portland, Oregon, United States on the northwest corner of SW 3rd Avenue and Washington streets. Since 1982, it has been on the National Register of Historic Places.
Architect Cass Gilbert worked on the American Renaissance-style Spalding building while also working on the Woolworth Building in New York City. Completed in 1911, it was considered a skyscraper.
The 103,824-square-foot (9,645.6 m2) building contains 12 above-ground floors, and its construction mimics a classical column: A base, a shaft, and a capital.
