Meidum is an ancient Egyptian archaeological site located about 60 kilometers south of Cairo. It is known for the Meidum Pyramid, which was originally built as a tomb for Pharaoh Sneferu during the Fourth Dynasty. The pyramid is unique because it started as a step pyramid and was later transformed into a true pyramid, showcasing the evolution of pyramid construction techniques. The site also features several other structures, including a mortuary temple and smaller pyramids for royal family members. Meidum is significant for its architectural innovations and provides valuable insights into the early development of pyramid design in ancient Egypt.
