The Bent Pyramids are one of the first attempts of the ancient Egyptians to create something extraordinary that can stand the test of time. This article’s main purpose is to offer every traveller all the information and facts about the wonders of the Bent Pyramid. This article was written by a group of very skilled and knowledgeable tour guides, Egyptologists, and travel consultants who know all the details surrounding the Great Bent Pyramid.

The Bent Pyramid was one of the first Pyramids to be ever built in ancient Egyptian history. The Bent Pyramid is a hidden gem that many travellers from all over the world seek to explore in great detail. The Bent Pyramid is known for its unusual shape, design, and brilliant design plus as one of the stepping stones for the construction process of the Egyptian pyramids. Many historians and Egyptologists have noted that the Bent Pyramid can showcase the evolution of how the pyramids of Egypt came to be.

The Bent Pyramid History

The Bent Pyramid was built by “Pharaoh Sneferu”, father of Khufu, the builder of the Great Pyramid in 2600 BC during the 4th dynasty, and was known as “The Southern Shining Pyramid”. The Bent pyramids are Sneferu’s second attempt to construct a smooth-sided true pyramid, but unfortunately, it was filled with many engineering issues.

It is considered to be a transitional pyramid rather than a true pyramid, between step-sided and smooth-sided pyramids. Due to its original steep angle, signs of instability appeared during construction, leading the builders to switch to a shallower angle to prevent collapse. Sneferu’s abandonment of the Meidum Pyramid may reflect a shift in ideology, moving from viewing the pyramid as a staircase to the stars to a symbol of the solar cult and primeval mound.

The Bent Pyramid is unique among Egypt’s approximately 90 pyramids for retaining much of its original polished limestone casing, which was removed over time. The name of the pyramid is “Snfrw Kha Sneferu,” which means “Sneferu is shining in the south” or “Sneferu is shining,” which was clad in polished Tura limestone.

Location of the Bent Pyramid

The Bent Pyramids are constructed in the desert on the west bank of the Nile, 40 km “25 mi” south of Cairo in the city of Dahshur.

The Bent Pyramid Dimensions

The material used for building the bent pyramid is Limestone, not mud brick. The Height of the Bent Pyramid is 104.71 metres (344 ft; 200 cu), beneath the bend is 47.04 metres (154 ft; 90 cu), and above the bend is 57.67 metres (189 ft; 110 cu). The Base of the bent pyramid is 189.43 metres (621 ft; 362 cu) at the base, 123.58 metres (405 ft; 236 cu) at the bend. The Volume of the Bent Pyramid is 1,237,040 cubic metres (43,685,655 cu ft). The Slope of the bent pyramid is 54°27′44″ below the bend and 43°22′ above the bend.

Why is the Bent Pyramid Bent?

The pyramid is called bent due to miscalculations & engineering problems regarding the structure and the limestone blocks which led to the weight of the entire pyramid being distributed inappropriately which resulted in the bottom section has of an angle of 54 degrees while the top half inclines 43 degrees causing the structure to be known as “The Bent Pyramid”.

Recent conclusions suggest that the slope change was not due to structural defects but geometric constraints. The initial steep angle made it difficult to construct stable ramps as the pyramid rose. To maintain a feasible ramp structure, builders reduced the angle to manage the geometry, as models and calculations were unavailable at the time. This geometric consideration also influenced future pyramids, which never exceeded a 53° gradient.

What is the Purpose of the Bent Pyramid?

One of the most unusual and unique constructions in Egypt and Probably the world is the bent “Blunted” Pyramid, built as the tomb of Pharaoh Sneferu (2575-2551 BC) the father of king Khufu, it was built as his second Pyramid as part of Sneferu’s plan to create an evolution to the pyramid construction and increase all the architectural innovation of the era.

It represents both a tomb and a reflection of changing spiritual and architectural concepts in ancient Egypt. The Bent Pyramid holds deeper historical significance due to its unique features and symbolic purposes. While designed as a burial place, the pyramid reflects evolving religious ideologies, marking a shift from step-sided pyramids to smooth-sided ones, symbolizing the solar cult and the sun god Ra.

Its bent shape highlights architectural experimentation with stability. The pyramid also symbolizes the union of heaven and earth, embodying Egypt’s cosmic and religious beliefs.

Who Built the Bent Pyramid?

The Bent Pyramid was constructed during the reign of Pharaoh Snefru, a.k.a Snofru or Soris (2620-2547 BC), who was the founder of the and the first Pharaoh of Egypt 4th Dynasty ( 2575 – 2465 BCE). He married Queen Hetepheres I, who was the mother of his son, Khufu, the founder of the Great Pyramids of Giza. He ruled Egypt for 24 years, from 2613 B.C. to 2589 B.C. He made many military campaigns to the lands of Nubia and Libya, and he constructed the first Egyptian ship, which was named “Praise of the Two Lands”.

He constructed three pyramids, the Red Pyramid, the Bent Pyramid, and the Medium Pyramid, which are located in the city of Dahshur. King Sneferu is considered one of the most innovative builders in ancient Egyptian history, responsible for developing the true smooth-sided pyramid structure. The Bent Pyramid was an experimental design, and its unusual shape starts at a steep angle and then slopes at a shallower angle halfway up, which is thought to be the result of structural concerns.

Scholars believe that the original angle of the pyramid (54 degrees) was too steep, causing instability. To avoid collapse, the builders adjusted the angle to 43 degrees partway through the construction. This change in angle is what gives the pyramid its distinctive “bent” shape. Pharaoh Sneferu’s experimentation with pyramid construction laid the foundation for his successor, Khufu, to build the Great Pyramid at Giza, considered one of the Seven Wonders of the Ancient World.

The Construction of the Bent Pyramid

The Bent Pyramid is considered the first true pyramid ever built, with a limestone polished design with smooth sides, the first of its kind. The Bent Pyramid complex is surrounded by an enclosure wall formed from yellowish-grey local limestone. The Bent Pyramid is 105 m (344 ft) with 54 degrees to 43 degrees, approximately one-third up to its full peak, because the angle was changed to avoid the structure collapsing after noticing signs of weakness in it, and the solution was to change its angle.

The Bent Pyramid underwent three distinct construction phases. The pyramid was laid out with a square base with precision, aligning it to the cardinal points (north, south, east, and west). The Egyptians had a steep pyramid with a base length of 157 meters and an angle of about 58° to 60°, which would have reached a height of 125 meters.

This steep design was impractical and was only partially built. Indirect evidence of this phase is found in the offset points within the descending corridors. The ancient Egyptians used ramps made of mudbrick, stone, or wood to move the heavy limestone blocks into place. The heavy blocks weigh tons, so they were dragged on sleds, lubricated with water to reduce friction, and pulled by large teams of laborers.

In the second phase, the angle was reduced to 54°, extending the base to 188 meters. The builders continued using inclined wall layers, similar to step pyramids, as trapezoidal stones were not yet produced. If maintained, this inclination would have resulted in a height of 129.4 meters, making the pyramid the third tallest in the world. However, construction stopped at 49 meters, and fine Tura limestone was used for facing.

The third & final phase saw the angle reduced to 43°, which is also the same angle of the Red Pyramid and later pyramids, with horizontal masonry layers. This change created the unique “bent” shape. The total height became 105 meters, with a volume of 1.44 million cubic meters. The upper portion also featured Tura limestone cladding.

Inside the Bent Pyramid

The Bent Pyramid offers a unique and fascinating exploration into ancient Egyptian architecture as it is one of the few that still retains much of its original smooth limestone casing, giving it a distinct appearance. The pyramid from the inside features a complex internal structure that includes several chambers, passageways, and unique architectural designs.

When entering the Bent Pyramid, everyone can walk through its narrow tunnels and climb down steep passageways to explore the two main chambers. The first chamber is located at a height of about 12 meters above the base, and the second chamber is directly beneath it, at the pyramid’s core. These chambers are connected by a series of passageways, and both have high, corbel-vaulted ceilings, which are designed to relieve the weight of the pyramid’s massive stone blocks.

The eerie silence inside the pyramid is totally captivating, as well as the dramatic difference in temperature between the hot, arid exterior and the cool, stone interior. The Bent Pyramid also has an unusual feature: a secondary entrance located on its northern face, which is not common in other pyramids, adding to its architectural intrigue.

The northern chamber of the Bent Pyramid has a hole in the roof, accessed by a long, unstable ladder, which leads to a rough passage connecting to the western entrance. The western entrance passage is blocked by two stone blocks that slid down ramps, unlike the typical vertical lowering in other pyramids. One block was lowered in antiquity, with a hole cut through it, while the other is still held up by ancient cedar wood.

Inside the chambers, a row of cedar beams has sparked debate. While some interpret them as structural supports for potential issues, they were part of a funerary support system, with no structural function, as some beams are set in mortar.

Bent Pyramid Chambers, Tunnels, and Tomb

The interior of the Bent Pyramid is known for its complex system of chambers, tunnels, and passageways, which reflect the early development of pyramid construction in ancient Egypt. The pyramid has two main entrances, as mentioned before, one on the north face and another on the west face, each leading to different sections of the pyramid’s interior.

Northern Entrance and Upper Chamber:

The northern entrance, which is located about 11 meters above ground level, leads to a descending passageway that ends in an antechamber. Everyone can access the upper chamber, which has a corbelled ceiling. This chamber is quite spacious and is thought to have been designed to hold the pharaoh’s sarcophagus, but no burial remains have been found in this chamber.

Western Entrance and Lower Chamber:

The western entrance leads to a second, lower chamber located at the pyramid’s base. This chamber is also accessed by a steep descending passage. The lower chamber is smaller and less elaborate than the upper one but features similar corbelled vaulting. This chamber is connected to the upper chamber through a sloping passageway.

Passageways and Tunnels:

The passages between the chambers are narrow and steep, making the pyramid a challenge. These passageways were likely designed to be difficult to navigate, possibly as a security measure to deter tomb robbers. The tunnels also highlight the structural engineering challenges faced by ancient builders, as they had to support the massive weight of the pyramid while carving out these internal spaces.

Tomb or Burial Site:

Despite the elaborate internal design, no sarcophagus or human remains have been discovered in the Bent Pyramid. This has led some scholars to suggest that Sneferu may not have been buried here, or that the tomb was looted back in the day. It’s also possible that the Bent Pyramid was never intended to serve as Sneferu’s final resting place, and that it was abandoned as a tomb once construction of the more stable Red Pyramid was completed.

The Satellite Pyramid of Bent Pyramid

The satellite pyramid is situated 55 meters south of the Bent Pyramid, which is believed to have been constructed to house the pharaoh’s ka (spirit). It stands 26 meters high and 52.8 meters long, its faces are inclined at an angle of 44°30′. The pyramid is built from thick limestone blocks arranged in horizontal layers and covered with fine Tura limestone. Its burial chamber is accessed via a descending corridor that begins 1.1 meters above ground on the northern face.

This 11.6-meter-long corridor inclined at 34° leads to a short horizontal passage, which connects to an ascending corridor sloped at 32°30′, ultimately leading to the central burial chamber. The corridor of the satellite pyramid design mirrors that of the Great Pyramid of Giza. Inside the burial chamber, a corbel-vaulted ceiling is found along with a 4-meter-deep shaft in the southeast corner, likely dug by treasure hunters. Like the Bent Pyramid, the satellite pyramid also featured an altar on its eastern side, flanked by two stelae.

Bent Pyramid Temple

There is a mortuary temple found on the east corner of the pyramid that was constructed in Tura limestone and later enlarged with mudbricks. The temple had an altar which was made from two large steles and three large blocks of limestone resembling the hieroglyph “htp” or “hotep,” which means offering.
