In a 90-minute special presentation, NOVA reveals the ancient secrets of how the pyramids were built by actually building one. A noted Egyptologist, Mark Lehner, and a professional stonemason, Roger Hopkins (This Old House), join forces in the shadow of the Great Pyramid of Giza to put clever and sometimes bizarre pyramid construction theories to the test.
