Dr Mark Lehner wants to know the answer to a question that rarely gets asked - Where and how did the workers who built the pyramids live? A popular misconception is that they were slaves, when in actual fact Dr Lehner states this is far from the truth. The builders of the pyramids were well fed with copious amounts of prime-cut beef, and graffiti found at the pyramids suggests that the builders were members of various tribes and clans.
In the video, Dr Lehner explains that he is looking to find out more about the people who built the pyramids - what their diet was, how they raised livestock and gathered crops, how they lived and other questions which remain about the workers.
To uncover his answers, Dr Lehner and his team undertake a rare type of excavation - one which is not in search of treasures or riches, but one which seeks to find answers.
One of the most impressive and startling structures in the world is the Great Pyramid of Giza in Egypt, yet the construction of it remains the subject of much debate and discussion to this very day.
Dr Mark Lehner, an archaeologist at the Oriental Institute of the University of Chicago, and Harvard Semitic Museum, has given an exclusive video interview to Heritage Key in which he explains what he and his team are doing in their latest excavation.
