Located between Milk Hill & Walkers Hill on the Pewsey Downs, the Alton Barnes horse is thought to have been cut by Robert Pile, the son of the creator of the Pewsey old horse, in 1812. An artist by the name of John Thorne was selected to design and cut the horse on the hill above the village. He agreed to excavate the horse to a depth of one foot and fill the cavity with chalk, and was paid £20 in advance for his trouble. Thorne employed a local man, John Harvey to do the work, but disappeared before the work was finished taking the £20 with him. The Alton Barnes horse faces south and measuries 165ft by 180ft. The figure is best viewed from the bridge on the Kennet and Avon canal one mile south of the horse , although it is also visible from the Horton to Alton Barnes road.
