From the start the horse would have required regular upkeep to stay visible. It might seem strange that the horse’s creators chose such an unstable form for their monument, but archaeologists believe this could have been intentional. A chalk hill figure requires a social group to maintain it, and it could be that today’s cleaning is an echo of an early ritual gathering that was part of the horse’s original function.
