This image depicts a brown horse rearing on its hind legs within an indoor equestrian arena, located in Mouscron, Belgium. The horse, exhibiting a white blaze on its face and a white sock on its lower left hind leg, is equipped with a yellow halter. A dark-colored lunge line or rope is attached to the halter, extending horizontally to the left, out of the frame. The arena floor consists of light brown sand or dirt footing with visible disturbances and hoof prints. The walls are light grey concrete, featuring a band of green algae or moss approximately halfway up, and a lower section clad with vertical dark brown panels. Two rectangular windows with obscured panes are visible on the far wall. The roof structure is composed of exposed metal beams and corrugated panels, with at least one translucent skylight allowing natural light into the facility. No human figures are visible in the frame.
