Who among us has not seen Stonehenge on his personal computer screen? Yes, it is a World Heritage Site, a legendary landmark and a British cultural symbol that has sparked the curiosity of many people, and which attracts many tourists from different regions around the world. The horizontal stones, which were transported directly from Wales, form a large ring, each 13 feet high, up to 7 feet wide and weighing about 25 tons, and was directed entirely eastward (sunrise) on the summer solstice.
