A series of experiments with atmospheric muons revealed an unexpected, previously unknown void inside the Great Pyramid of Giza. Three different experimental techniques were used in order to confirm the existence of the void, all indicating the same results about its location, length and volume. In this talk, I’m going to present you some basic concepts about muons and their interactions inside the pyramid. Then, I’m going to give you an overview of the known structure of the pyramid and move on to describe each one of the techniques, namely: nuclear emulsion, scintillators and micro-pattern gaseous detectors. For each one of them I will provide information about the experimental set up, the data analysis and results as well as how these different types of detectors work. Finally, I will make a comparison between the methods used and conclude with questions about the structure of the void and the future of this mission.
