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.
