A dolmen is a type of megalithic structure, typically consisting of two or more large stones supporting a horizontal stone slab. These ancient tombs are often found in various parts of the world, particularly in Europe and Asia, and date back to the Neolithic and Bronze Ages. Dolmens are believed to have served as burial sites or ceremonial spaces. The construction of dolmens involved significant effort, as large stones were transported and arranged without modern tools. They are often associated with ancient cultures and are considered important archaeological sites, providing insights into early human societies and their burial practices.
