A necropolis is a large, ancient cemetery or burial site, often associated with a specific culture or civilization. The term comes from the Greek words "nekros," meaning dead, and "polis," meaning city. Necropolises were typically located outside city limits and contained elaborate tombs, mausoleums, and burial structures, reflecting the beliefs and practices surrounding death and the afterlife. Many famous necropolises, such as the Valley of the Kings in Egypt and the Catacombs of Rome, provide valuable insights into the customs, art, and architecture of the societies that created them. These sites often serve as important archaeological resources, helping researchers understand historical populations and their rituals related to death.
