A megalith is a large stone that has been used to construct a structure or monument. These impressive stones are often associated with ancient cultures and can be found in various parts of the world. Megaliths are typically arranged in specific patterns, and they are believed to have served religious or ceremonial purposes. Famous examples include the Stonehenge in England and the Carnac stones in France. Megaliths can vary in size and shape, ranging from single upright stones to massive stone circles. They provide valuable insights into the lives and beliefs of the people who built them. Archaeologists study megaliths to learn more about ancient societies and their connection to the earth and sky.
