First National Center (Art Deco skyscraper)

Completed in 1931, First National Center is an Art Deco steel-frame skyscraper in downtown Oklahoma City. It was one of the city's earliest high-rise office buildings and dominated the skyline for much of the 20th century. The building later underwent major rehabilitation and reuse efforts in the 21st century to accommodate mixed commercial and residential functions. Architectural features include ornamental limestone cladding and tiered setbacks characteristic of Art Deco design.
