megalithic monument(mĕgəlĭth`ĭk) [Gr.,=large stone], in archaeology, a construction involving one or several roughly hewn stone slabs of great size; it is usually of prehistoric antiquity. These monuments are found in various parts of the world, but the best known and most numerous are concentrated in Western Europe, including Brittany, the British Isles, Iberia, S France, S Scandinavia, and N Germany. Aside from the standing stones and stone heaps that are still raised occasionally as boundary marks or memorials of personal and public events, most megalithic monuments seem to have been erected for funerary and religious purposes. The Western European megaliths were constructed during the Neolithic and the Bronze Age and are believed to range in date from c.4000 B.C. to 1100 B.C. Most chamber tombs were probably built during the 4th millennium B.C., and the stone circles generally date somewhat later. Megalithic monuments may be divided into four categories: the chamber tomb, or dolmendolmen
[Breton,=stone table], burial chamber consisting of two or more upright stone slabs supporting a capstone or table, typical of the Neolithic period in Europe. See megalithic monuments.

[Breton,=long stone], in archaeology, name given to the single standing stones of Western Europe, and by extension to those of other lands. Their size varies and their shape is rough and squared, tapering toward the top. See megalithic monuments.

in archaeology, a burial mound. Earth and stone or timber are the usual construction materials; in parts of SE Asia stone and brick have entirely replaced earth. A barrow built primarily of stone is often called a cairn.
