Why did the ancient Egyptians build a pyramid with a sudden, sharp bend?
In short: The Bent Pyramid of Dahshur is a 4,600-year-old architectural puzzle. Its unique double slope, shifting from 54 to 43 degrees, marks a pivotal moment in pharaonic history. While long neglected by researchers, recent explorations into its hidden vertical shafts and internal chambers are finally revealing how Sneferu pursued the perfect pyramid.
Commissioned by the pharaoh Sneferu in the 25th century B.C., the Bent Pyramid was the first attempt at constructing a true, smooth-sided pyramid from the ground up. Standing 331 feet tall, the structure is defined by its dramatic change in angle at the mid-way point. Experts believe this shift was a desperate structural adjustment; as construction progressed, cracks appeared in the masonry, signaling that the original, steeper design was fundamentally unstable.
The pyramid serves as a testament to the trial-and-error nature of ancient Egyptian engineering. Sneferu’s architectural journey began with the stepped pyramid at Meidum, which was later modified into a smooth-sided form, though its acute angle proved problematic. Following the Bent Pyramid, Sneferu commissioned a third structure before finally achieving success with the Red Pyramid, which featured a consistent 43-degree angle and is widely considered the pharaoh’s 'perfect' monument.
Beyond its external geometry, the Bent Pyramid contains mysterious internal features, including a 15-meter vertical shaft known as the 'Chimney.' While the pyramid was closed to the public from 1965 until 2019, recent restoration efforts—including repairs to corridors, chambers, and stairs—have allowed researchers and tourists to access the interior. Despite these advancements, the exact purpose of certain architectural elements remains debated, and the final resting place of Sneferu continues to elude archaeologists, leaving open the possibility that he may have been interred within this very structure.
