Kist-vaen (The).

A rude stone sepulchre or mausoleum, like a chest with a flat stone for a cover

“At length they reached a grassy mound, on the top of which was placed one of those receptacles for the dead of the ancient British chiefs of distinction, called Kist-vaen, which are composed of upright fragments of granite, so placed as to form a stone coffin. .”—Sir Walter Scott: The Betrothed, chap. xxix
