It is thus called the old places of cemeteries, places that are the last resting place of human burials giving way to a city of dead or corpses. Its etymology from the Greek comes from the combination of two words, Necro which means dead or corpse and Polis which means city, hence its etymology of city of the dead which normally refers to places of large old cities, which are an important part of the history of the city, as well as the ancient civilizations that were forgotten over time.

They are characterized by being large expanses of land with monuments as a reminder of a past time, of people of importance in society or of a specific community, with characteristic monuments made up of burial chambers where they housed entire families of past generations, which in their most are still buried there, or with bodies mummified by the passage of time. They are scattered throughout the world from ancient medieval churches of the 11th and 12th centuries, their presence guards secrets of humanity since the Romans and the Egyptians; its birth as such of existence varies, but the main and common reason is the religiosity of the time since the kings and pharaohs of ancient Egypt were buried in luxurious chambers with their personal belongings, with care so that the passage to the new life is not unpleasant and in an appropriate way, carrying with them the hierarchy that they possessed in life, and they avoided looting by being in depths and very hidden. In ancient Rome, the Romans were forbidden to bury their loved ones within the city, so they created a separate city with ornate monuments for sacred purposes, that is, to be a sacred and holy land for the last eternal rest.
