A cemetery, burial ground, gravesite or graveyard is a place where the remains of dead people are buried or otherwise interred. The word cemetery (from Greek κοιμητήριον, "sleeping place") implies that the land is specifically designated as a burial ground and originally applied to the Roman catacombs. The term graveyard is often used interchangeably with cemetery, but a graveyard primarily refers to a burial ground within a churchyard.The intact or cremated remains of people may be interred in a grave, commonly referred to as burial, or in a tomb, an "above-ground grave" (resembling a sarcophagus), a mausoleum, columbarium, niche, or other edifice.
