This valley in Fayoum was called the Valley of the Watermelon because it contains rounded stones that resemble the shape of a watermelon, but are larger in size. These round stones have become one of the secrets that have not been revealed how they were formed until now, as geologists have developed more than one theory, but the theories that have been developed do not justify their multiple colors such as scarlet, pink and brown. And woven around these rocks many legends and myths, as some residents of Fayoum still believe that these rocks are actually watermelons petrified with the passage of millions of years.
