A tumulus (plural tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or kurgans, and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus.
A dolmen (...) is a type of single-chamber megalithic tomb, usually consisting of two or more vertical megaliths supporting a large flat horizontal capstone or "table". Most date from the early Neolithic (4000–3000 BC) and were sometimes covered with earth or smaller stones to form a tumulus. [...] In many instances, the covering has weathered away, leaving only the stone "skeleton" of the mound intact.
The etymology of the German: Hünenbett, Hünengrab and Dutch: hunebed - with Hüne/hune meaning "giant" - all evoke the image of giants buried (bett/bed/grab = bed/grave) there. [5]
