Designed by R. Duane Conner
1959
Oklahoma City University (UCO) campus

To provide the 3,500-seat structure with unimpeded views of the basketball court, architect R. Duane Conner incorporated a thin-shell, hyperbolic paraboloid roof design that was supported by four exterior columns with no need for obstructing interior columns.  When it was constructed, it was one of the largest examples of a hyperbolic paraboloid roof in the world.  The building served the school for nearly 50 years before being demolished in 2005.
