Bill Brown & Trevor Grassi: The Secret Underworld of Giza

Trevor Grassi is an independent researcher studying prehistoric evidence of advanced civilizations, focusing on the Great Pyramids, Sphinx, and the underground of Giza. He's visited over a dozen countries and over a hundred pyramids, temples, and sacred sites. He's studied megalithic stonework, mythology, astrology, math, and geometry of ancient cultures in an attempt to reconstruct the 'sacred sciences' of the last Golden Age, and he has written a book series that is soon to be published and is currently working on a long format documentary series with Bill Brown, called 'The Secret Underworld Of Giza'.

William (Bill) Brown is a retired civil engineer turned Gizatologist, who has spent the last 20 years investigating the mysteries of the Giza Plateau. He has been deep underground at Giza many times and in many locations. Bill has also carried out ground penetrating radar scans at many sites at Giza as well as at the Hawara Labyrinth site in the Fayoum Oasis. He has made many discoveries at both sites. He is currently leading a project attempting to excavate and access many underground chambers and tunnels at Giza with the IRGE (International Research Group, Egypt) and Mission Pharaoh, an international collection of foundations supporting his work.
