A huge stone or rock slab, used in prehistoric monuments and constructions. The word megalith comes from the combination of two Greek words meaning 'big' and 'stone' and may also be used to describe prehistoric monuments which consist of large stones, such as stone circles, stone rows, dolmens and chambered barrows. A monolith is a very large single block of stone, also often erected as a monument, shrine, astronomical observatory or marker. Megalithic designates a people that builds using megaliths or something that was built with megaliths.
Megaliths can range in size from two feet to twenty.
Major megalithic monuments in Europe include Stonehenge and Avebury in England, the chambered mounds of Knowth, Dowth and Newgrange in Ireland, Callanish stone circle and avenues in the Outer Hebrides and the stone rows at Carnac in Brittany.
