Tulsa is a hub of art deco and contemporary architecture, and most buildings of Tulsa are in either of these two styles.
Prominent buildings include the BOK Tower, the second tallest building in Oklahoma; the futurist Oral Roberts University campus and adjacent Cityplex Towers, a group of towers that includes the third tallest building in Oklahoma; Boston Avenue Methodist Church, an Art Deco church designated as a National Historic Landmark; and the BOK Center, an 18,000-seat arena in downtown Tulsa.
