Pyramid of Khafre is a monumental construction in Egypt, Africa. It is associated with Giza Plateau. UNESCO World Heritage List #86 gives its chronology as “c. 2570 BCE, reign of Khafre.” Its listed material is Limestone. Its height is listed as 143.5 m (estimated). UNESCO World Heritage List #86 also records: “Royal tomb.”
Second pyramid of Giza, still capped with part of its original polished casing.
The pyramid exhibits a high degree of architectural precision, evidenced by its steep 53° 10' slope and its orientation to the cardinal directions. Modern surveys using Total Station measurements confirm minimal deviation from true north, indicating that Old Kingdom builders utilized sophisticated surveying or astronomical methods to achieve this alignment.
The interior of the pyramid features a burial chamber carved directly into the bedrock, which is topped by a gabled roof of limestone beams. Within this space, a sarcophagus was fashioned from a solid block of granite and partially embedded into the floor, demonstrating the use of durable stone materials for royal funerary equipment.
Originally reaching a height of 143.5 meters, the pyramid is a monumental structure that appears taller than its neighbor due to its placement on a higher bedrock foundation. Its scale is further emphasized by the massive megalithic blocks used in the associated Valley Temple, some of which are estimated to weigh up to 400 tonnes.
The construction of the pyramid and its temple complex involved the movement of significant quantities of stone, including Tura limestone and red granite. The catalogue records that these materials were sourced and transported to the Giza plateau to facilitate the monument's cladding and the structural requirements of the mortuary temple.
The pyramid's construction reflects a high level of technical control, from the deliberate excavation of the bedrock to create a level foundation to the precise alignment of its northern face. While the casing stones show minor edge irregularities, these are interpreted by researchers as potential results of seismic activity or specific pre-placement cutting techniques rather than a lack of precision.
The pyramid is distinguished by its unique material composition, retaining original cladding of Tura limestone on its upper sections and pink granite at its base. This combination of materials highlights the aesthetic and structural choices made during the Old Kingdom, with the limestone providing a polished finish that remains partially visible today.
Modern surveys utilizing Total Station measurements have confirmed that the pyramid is aligned very closely to the cardinal directions with minimal deviation from true north. This high level of precision suggests that Old Kingdom architects employed advanced surveying or astronomical methods to establish the monument's orientation. While highly accurate, researchers have noted small systematic differences between the alignment of Khafre's pyramid and that of Khufu, indicating distinct surveying events or slightly different methodologies for each structure.

The burial chamber was excavated from a pit in the bedrock rather than built into the masonry. It is a rectangular room measuring 14.15 by 5 meters, oriented east-west, and features a gabled roof made of limestone beams. Inside, Giovanni Belzoni discovered a sarcophagus carved from a solid block of granite, which was partially sunk into the floor. The chamber also contains two small rectangular holes in the walls that resemble the 'air shafts' found in the Great Pyramid.
Khafre's monument is the only Giza pyramid that retains a significant portion of its original cladding, which covers the top third of the structure. The bottom course of these casing stones was originally fashioned from pink granite, while the remaining upper sections were finished in Tura limestone. Modern examination of these surviving blocks reveals that their corner edges are not perfectly straight but are staggered by a few millimeters, possibly due to seismic settling or pre-placement cutting techniques.
To compensate for the natural slope of the Giza plateau, the pyramid's builders employed significant earthworks at the foundation level. The northwest corner was excavated 10 meters deep into the rock subsoil, while the southeast corner required building up to create a level base. The core of the pyramid also incorporates a natural rock outcropping, similar to the Great Pyramid. At the northwest corner, the bedrock was specifically fashioned into steps to support the massive masonry courses.
The Valley Temple of Khafre is remarkably well-preserved, featuring a T-shaped hallway with square pillars made of solid granite and floors paved in alabaster. The exterior was built from limestone blocks, some weighing over 100 tonnes, sheathed in red granite. In 1858, archaeologist Auguste Mariette discovered a famous diorite statue of Khafre within this complex. The temple's floor still contains sockets that once held 23 statues of the king, though these columns and statues have since been plundered.
In the late 1960s, physicist Luis Alvarez led a joint American-Egyptian team to search for hidden chambers within the pyramid using muon transmission imaging. This experiment involved recording the penetration of cosmic rays to detect voids in the masonry. Although the project was briefly interrupted by the 1967 Six-Day War, the team continued their analysis until 1969. Alvarez eventually reported to the American Physical Society that no additional chambers were found in the 19% of the pyramid's volume they successfully surveyed.
The Pyramid of Khafre, constructed around 2550 BC, originally reached a height of 143.5 meters (471 feet) with a base length of 215.25 meters. While it currently stands at 136.4 meters, it often appears taller than the neighboring Great Pyramid because it was built on a bedrock foundation situated 10 meters higher on the Giza plateau. Notably, its slope of 53° 10' is steeper than that of Khufu's pyramid, which rises at an angle of 51° 50' 24".
Khafre's mortuary temple was the first to incorporate the five standard elements found in later Old Kingdom funerary complexes: an entrance hall, a columned court, five statue niches, five storage chambers, and an inner sanctuary. The temple was constructed using massive megalithic blocks, the largest of which is estimated to weigh 400 tonnes. Although now largely in ruins, it originally housed over 50 life-sized statues of the pharaoh, which were later removed and recycled, possibly during the reign of Ramses II.
The pyramid was first explored in modern times by Giovanni Belzoni on March 2, 1818, who located the original northern entrance and found the burial chamber empty except for a broken sarcophagus. John Perring conducted the first complete exploration in 1837. A tragic event occurred in 1932 when American mountaineer Elbridge Rand Herron was killed instantly after falling while attempting to climb the pyramid's exterior. Historical records from 1372 indicate the pyramid was also opened during the medieval period.
The pyramid features two separate entrances on its northern face: one located 11.54 meters up the side and another at the base. These passages are offset 12 meters to the east of the pyramid's centerline. One theory suggests this dual system resulted from a plan to shift the pyramid's base 30 meters further north to exceed the size of Khufu's pyramid. Alternatively, the two entrances may represent a mid-construction design change, a common occurrence in earlier Old Kingdom pyramid projects.
