A necropolis is a large, ancient cemetery or burial site, often associated with a specific city or civilization. The term comes from the Greek words "nekros," meaning dead, and "polis," meaning city. Necropolises were typically located outside city walls and contained elaborate tombs, mausoleums, and burial structures, reflecting the beliefs and customs of the people who built them. Many famous necropolises, such as the Valley of the Kings in Egypt and the Catacombs of Rome, provide valuable insights into ancient cultures. These sites often feature intricate artwork, inscriptions, and artifacts that help historians understand the social, religious, and artistic practices of the time.
