large, indoor arena packed with spectators seated in tiered rows around the perimeter. The arena floor is covered in light brown sand. In the center of the arena, a white horse adorned with a red and white saddle and decorative tack is being led by a person in a black and white outfit. The person appears to be guiding the horse through movements, and at one point the horse rears up slightly on its hind legs. The architecture of the building includes large, rounded windows along the upper portion of the walls, allowing natural light to illuminate the space.
