Megalithic tombs are large burial structures made from massive stones, often found in various parts of the world. These ancient monuments were typically constructed during the Neolithic and Bronze Age periods and served as final resting places for important individuals or communities. They often feature intricate designs and alignments with celestial events. Common types of megalithic tombs include dolmens, which consist of a large flat stone supported by upright stones, and passage graves, which have a long passage leading to a burial chamber. These structures provide valuable insights into the social and spiritual practices of early human societies.
