Who conceived this amazing monument? When? How? Why? Is it just the ‘guardian of the Giza Pyramids’ or something else? What else? Why the lion-man symbolism? Why is it gazing towards cardinal east? Did it have a name? Is it connected to the Pyramids? What is the meaning of the megalithic temples next to it? Is there a secret chamber underneath the Sphinx as many have claimed? Bestselling author and engineer Robert Bauval will discuss all these issues in a fully illustrated lecture.
