The J.S. Dorton Arena (originally called the State Fair Arena) is one of the most celebrated and iconic structures in North Carolina. Originally designed as a livestock exhibition and judging pavilion—sometimes referred to as the “Cow Palace”—for the North Carolina State Fair, the 7,610-seat arena has also been a venue for music concerts, sporting events, circuses, and university graduation ceremonies. Its saddle-like roof approximates a hyperbolic paraboloid that spans 300 feet by 300 feet without intermediate columns.
