The Secret Underworld of Giza / Trevor Grassi

In this exclusive Megalithic Marvels interview, I sit down with explorer, researcher and filmmaker Trevor Grassi. Earlier this year, Trevor was instrumental in breaking the news to the world regarding the Khafre Pyramid scans. Now he is working tirelessly to recover the lost wisdom of prehistoric civilizations in Egypt and beyond. In this in-depth discussion, I ask Trevor about the following: - Khafre pyramid scans update - Secret tunnels and massive chambers beneath the Sphinx - The Hawara labyrinth and the 40 meter metal object discovered - Trevor's quest to uncover the Giza underworld - A possible secret entrance at the 'Menkaure' pyramid - Fayoum's mysterious Qasr Al Sagha megalithic temple - The sealed gates of the 'Second Sphinx' and the 100+ blocked entrances ...and much more!!
