Cerne Abbas Giant
Unlike many other geoglyphs mentioned on this list, the Cerne Abbas Giant, located near the village of Cerne Abbas in Dorset, England, is likely not a prehistoric creation. The earliest mention of its existence occurs as recently as the 17th century. Even so, its creation and meaning remain shrouded in mystery.
The figure is most notable for its depiction of a giant man with an erect penis. It has been called "Britain's most famous phallus," and has become a popular tourist attraction.
