A cist is a small stone-lined grave, typically built during the Bronze Age, in which a single body or a cremated remains deposit was placed, often accompanied by a ceramic pot or small personal objects, then sealed with a capstone and covered over with earth. They are among the most personal of prehistoric monuments, intimate in scale, intended for one person rather than a community, and they appear across Ireland in their hundreds, most of them known only by a grid reference and a classification number.
