A necropolis (Greek plural: necropoleis; Latin plural: necropoles) is a large cemetery or burial ground, usually including structural tombs. The term comes from the Greek νεκρόπολις - nekropolis, literally meaning "city of the dead". Apart from the occasional application of the word to modern cemeteries outside large towns, it is chiefly used to refer to burial grounds near the centers of ancient civilizations, such as an abandoned city or town. The term "necropolis" is also occasionally used in fantasy fiction to describe a city overrun by fictional undead.
Grave field is a term for prehistoric burial grounds that do not include any above-ground structures or markers. These include row graves, urnfields, tumuli, etc.
