Types of megalithic structures

Megaliths in Greek language means “big stone” and are stone structures relating to the prehistoric period.

These structures were erected without any connecting mortar (cement or lime), and just evolved. A new name – “megaliths” – was first performed in 1849 in his book “Cyclops Christianus,” written by English researcher A. H., and in 1867, the term was adopted at the Paris Congress. Megalithic structures are large blocks of hewn stones, which can consist of one large stone or group of stones.
