Stilts are poles, posts or pillars use to allow a person or structure to stand at a certain distance above the ground. Walking stilts are poles equipped with steps for the feet to stand on, or straps to attach them to the legs, for the purpose of walking while elevated above a normal height. In flood plains, and on beaches or unstable ground, buildings are often constructed on stilts to protect them from damage by water, waves or shifting soil or sand. Stilts have been used for many hundred years .
