Continuing the previous article. Recall that some experiments have proved that the construction of Stonehenge is technically possible. It was much easier to erect a huge stone slab. A pit was dug in advance at the site and the stone block was then dragged to the very edge of the pit so that it overhanged slightly. A small cart loaded with stones was placed on top of the concrete block. Then it was slowly pulled up to the pit; little by little the center of gravity shifted, and the large block slipped into the pit. It took a little more effort to put it upright, but in the end it was done with a triangular wooden frame and a team of volunteers pulling the ropes. The last operation - laying a horizontal cofferdam on two standing stones to create a complete trilithon - was done with a wooden deck. However, engineers and archaeologists agreed that the more likely method was to gradually climb to the desired height with the use of levers and wooden support, when people simultaneously lay on
