A new study by a team of engineers from two Beijing universities and Princeton University reveals how ancient Chinese workers hauled 100 ton plus stones over a distance of 43 miles to build the Forbidden City. The study published in Proceedings of the National Academy of Sciences states that workers dug wells every 500 meters in the deep winter to reach water that they could pour over the ground to create ice pathways that helped them slide the stones. They were able to determine this by studying the friction that different methods of hauling produce.
