Ty-Lia (Île Grande) Passage Grave

A passage grave (sometimes hyphenated) or passage tomb consists of a narrow passage made of large stones and one or multiple burial chambers covered in earth or stone. Megaliths are usually used in the construction of passage tombs, which usually date to the Neolithic. Those with more than one chamber may have multiple sub-chambers leading off from the main burial chamber. One common layout, the cruciform passage grave, is cross-shaped. Sometimes passage tombs are covered with a cairn, especially those dating to later times. Not all passage graves have had record of bodies being contained in them. One such example is Maeshowe.
