Church monuments – within a church (or tomb-style chests in a churchyard) may be places of interment, but this is unusual; they more commonly stand over the grave or burial vault rather than containing the actual body and are therefore not tombs
Crypts – often, though not always, for interment; similar to burial vaults but usually for more general public interment
Mausolea (including ancient pyramids in some countries) – external free-standing structures, above ground, acting as both monument and place of interment, usually for individuals or family group
Megalithic tombs (including Chamber tombs) – prehistoric places of interment, often for large communities, constructed of large stones and originally covered with an earthen mound
Rock-cut tombs, a form widespread in the ancient world, in which the tomb is not built but carved out of the rock and can be a free-standing building but is more commonly a cave, which may be extensive and may or may not have an elaborate facade.
Sarcophagi – stone containers for bodies or coffins, often decorated and perhaps part of a monument; these may stand within religious buildings or greater tombs or mausolea
Tumulus- (plural: tumuli) A mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds, Hügelgräber or kurgans', and can be found throughout much of the world. A cairn (a mound of stones built for various purposes), might also be originally a tumulus. A long barrow is a long tumulus, usually for numbers of burials.
As indicated, tombs are generally located in or under religious buildings, such as churches, or in cemeteries or churchyards. However, they may also be found in catacombs, on private land or, in the case of early or pre-historic tombs, in what is today open landscape.
