Megalith

Large stone used to build a structure or monument

A megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. They are found worldwide, but more than 35,000 megalithic structures have been identified across Europe, ranging geographically from Sweden in the north to the Mediterranean Sea in the south. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from Ancient Greek μέγας (mégas), meaning "great", and λίθος (líthos), meaning "stone".
