Giant Ringstones, Harappa 29

These giant ringstones are similar to ones found in Mohenjo-daro and Dholavira. Local legend claims they were the rings of a giant 17th century saint (Baba Nur Shah) who is buried on Mound AB. Early excavators believed that were significant to the ancient Indus religion. Today, archaeologists think that they were used to secure wooden posts at gateways to the city.
