Dolmen, a table like structure consisting of three or more upright stones supporting a large flat horizontal capstone, is one of various types of megalithic monuments found in various parts of India. As these structures hold cultural significance as tangible remnants of ancient civilizations and their burial customs, solike other archaeological sites, Dolmens require conservation efforts to protect them from natural degradation, vandalism and urbanization. The present review article is an attempt to provide the detailed information regarding various dimensions of Dolmens, with special reference to India, like its structure, material of construction, construction technique and form, purpose and function, distribution, relation with later architecture, living tradition and relation between past and present. The work is based on the secondary sources of the data and the description is illustrated through pencil sketches drawn by the author herself. The present study is crucial for students and other interested readers to understand the chronological, historical, cultural and social contexts of dolmen sites in India. It would also stimulate to make collaborative efforts between archaeologists, historians, anthropologists, local communities and government agencies essential for the preservation and study of these invaluable heritage sites.
