The Arena in Diriyah is located in Diriyah, Saudi Arabia. Inspired by the Najdi architectural tradition and geological formations, it echoes the imagery of ancient city fortresses and palaces. With a construction area of approximately 76,000 square meters, the facade design features a luminous "digital waterfall," creating a visual beacon through zigzag transparent panels and triangular perforations that captivate audiences while blending traditional and modern dynamic effects.
