Bent Pyramid Egypt – Unique Design & History of Sneferu’s Tomb
Bent Pyramid Egypt – Unique Design & History of Sneferu’s Tomb
The Bent Pyramid was built by King Sneferu, the first king of Egypt’s 4th Dynasty. It is called the Bent Pyramid because its angle changes partway up the structure, reflecting an engineering problem during construction. The lower section was built at 55°, then the angle was reduced to 43° as the weight of the stone blocks created instability.
This guide explains where the pyramid stands, how its unusual design developed, what lies inside, and how you can visit it as part of a day tour from Cairo. It is also referred to as the Curved Pyramid or Crooked Pyramid.

What Is the Bent Pyramid?
The Bent Pyramid is a 4th Dynasty royal pyramid built for King Sneferu at Dahshur, south of Cairo. It is known for the unusual change in the angle of its sides, which gives the monument its distinctive profile. The pyramid rises to about 101 meters (332 feet), and much of its original limestone casing remains in place, offering a rare view of the smooth outer finish used on Old Kingdom pyramids.
The change in slope reflects a problem that developed during construction. The builders began with a steep angle of 55 degrees, but the increasing load of the stone blocks caused instability, so the upper section was built at a gentler angle of 43 degrees. This adjustment left the pyramid with its characteristic double-angled form and made it an important example of the experimentation that shaped the development of smooth-sided pyramids.

Bent Pyramid Location
Where is the Bent Pyramid located? The Bent Pyramid stands at Dahshur, about 40 km south of Cairo, within the ancient Memphis necropolis and the Memphis and its Necropolis UNESCO World Heritage Site. The Red Pyramid is about 1,8 km north of the Bent Pyramid, while Saqqara, home to the Step Pyramid of Djoser, lies farther north. Unlike the busy Giza Plateau, Dahshur generally receives far fewer visitors, offering a quieter setting for exploring Egypt’s ancient pyramids.
History of the Bent Pyramid
The Bent Pyramid was built during the reign of King Sneferu, the first king of Egypt’s 4th Dynasty who ruled from 2613 to 2589 BC. It followed the earlier Step Pyramid of King Djoser at Saqqara, which marked the beginning of monumental pyramid construction in Egypt. By Sneferu’s reign, royal builders were moving toward a new design with smooth, rather than stepped, outer faces.
The Bent Pyramid at Dahshur represents an important stage in this architectural development. It was intended to be a complete smooth-sided pyramid, but changes to its design during construction prevented it from achieving the planned form. Sneferu then commissioned another pyramid nearby, the Red Pyramid, which became Egypt’s first successfully completed true pyramid. Together, Sneferu’s pyramids document a crucial period of experimentation that led to the fully developed pyramid form seen later at Giza.

Unique Design and Architecture
The Bent Pyramid’s unusual profile comes from the way its builders changed the slope of the structure during construction. The lower section rises steeply, while the upper section has a noticeably gentler slope. Rather than treating this change simply as a visual feature, the design provides evidence of how ancient Egyptian builders responded to structural challenges while developing the smooth-sided pyramid form.
The Ministry of Tourism and Antiquities explains that the original 55-degree angle had to be reduced to 43 degrees because the increasing load of the stone blocks caused instability. The change altered the shape of the monument but allowed construction to continue, leaving the Bent Pyramid as an important example of the engineering decisions made during the transition from stepped pyramids to later smooth-faced designs.
Pharaoh Sneferu – The Builder
King Sneferu was the first king of Egypt’s 4th Dynasty and one of the most important figures in the development of pyramid architecture. He is associated with three major pyramid projects: the Meidum Pyramid, the Bent Pyramid at Dahshur, and the Red Pyramid. Together, these monuments show how royal builders experimented with different designs and construction techniques during his reign. Egypt’s Ministry of Tourism and Antiquities describes Sneferu’s reign as a pivotal period in the development of pyramid-building technology.
The Bent Pyramid was part of this wider architectural experimentation. After the Meidum Pyramid, which he is generally credited with completing, Sneferu commissioned the Bent Pyramid and later the Red Pyramid at Dahshur. The Red Pyramid ultimately became Egypt’s first successfully completed true pyramid.
Sneferu was also the father of King Khufu, who succeeded him and built the Great Pyramid of Giza. The architectural experience gained during Sneferu’s reign helped establish the foundations for the monumental pyramid building that reached its greatest scale under his son.
Taken together, Sneferu’s Pyramid projects show how experimentation in design and construction gradually led to the smooth-sided pyramids of the Old Kingdom.

Inside the Bent Pyramid
The Bent Pyramid has two entrances, one on the northern side and another high on the western side. The northern entrance has modern wooden stairs for visitor access, while the western entrance is positioned higher in the pyramid. Each entrance leads through its own internal route to a chamber with a corbelled roof. The chamber reached from the northern entrance lies below ground level, while the chamber associated with the western entrance is built higher within the body of the pyramid.
The different levels of the two chambers reflect the unusual internal arrangement of the monument. The corbelled roofs were formed by successive layers of stone projecting inward as they rise, creating the stepped appearance of the ceilings. The upper chamber also contains remains of cedar wood beams placed against its walls, providing physical evidence of structural measures used within the pyramid. Their precise purpose should not be assumed without further evidence.
Visit the Bent Pyramid on a Guided Day Tour
Most visitors see the Bent Pyramid as one stop on a wider day trip from Cairo rather than as a standalone visit. The Saqqara, Memphis & Dahshur Day Tour from Cairo covers the Step Pyramid at Saqqara, the open-air museum at Memphis, and both the Bent and Red Pyramids at Dahshur. The tour includes a private Egyptologist guide, private transfers, entrance fees, and lunch.
