A megalith is a large stone which has been used to construct a structure or monument, either alone or together with other stones. Megalithic describes structures made of such large stones, utilizing an interlocking system without the use of mortar or cement.
The word ‘megalith’ comes from the Ancient Greek μέγας megas meaning great, and λίθος lithos meaning stone. Megalith also denotes an item consisting of rock(s) hewn in definite shapes for special purposes.
