The Meidum Pyramid, attributed to Pharaoh Huni and completed by Sneferu, marks a pivotal point in pyramid evolution. Originally a step pyramid, it was later converted into a true pyramid, making it one of the earliest attempts at smooth-sided design. However, the structure partially collapsed in antiquity—possibly due to poor construction methods or design changes—leaving its core exposed. This collapse has helped archaeologists better understand ancient Egyptian building techniques. Despite its ruined state, Meidum remains architecturally significant and is surrounded by subsidiary tombs and mastabas. The site reflects both ambition and experimentation at the dawn of the Fourth Dynasty.
