A chamber tomb is a tomb for burial used in many different cultures. In the case of individual burials, the chamber is thought to signify a higher status for the interree than a simple grave. Built from rock or sometimes wood, the chambers could also serve as places for storage of the dead from one family or social group and were often used over long periods for multiple burials. There are numerous terms for them depending on the period, design and region in question. Most were constructed from large stones or megaliths and covered by cairns, barrows or earth, but the term is also applied to tombs cut directly into rock and wooden-chambered tombs covered with earth barrows. Grave goods are a common characteristic of chamber tomb burials.
