Stonehenge, located in the south of England, is one of the most mysterious ancient monuments in the world. It consists of a circle of massive stones, some of which weigh over 20 tons. Archaeologists believe that it was constructed more than 4,000 years ago, but its exact purpose remains unclear. Some experts think it was used for religious ceremonies, while others believe it functioned as a kind of calendar or astronomical observatory. Transporting and arranging the stones without modern equipment must have required remarkable planning and cooperation. Stonehenge continues to attract researchers and tourists from around the world who are fascinated by its history and the secrets it holds.
