A huge stone monument or structure. Stonehenge is perhaps the best known example of megalithic construction.
A structure consisting of large stones.
A megalith is a large stone which has been used to construct a structure or monument either alone or with other stones. Megalithic means made of such stones, but uses an interlocking system without the use of mortar or cement. The word megalith comes from the Ancient Greek megas meaning great, and lithos meaning stone.
