Great Pyramid of Giza

Giza Plateau

For more than 3,700 years the Great Pyramid was the tallest human-made structure in the world. It was built for Khufu, second king of the 4th Dynasty, during his reign (c. 2589–2566 BCE; dates vary between chronologies), and is the largest of the three pyramids on the Giza Plateau.

Its base is almost a perfect square of 230.35 m a side, and its sides face the cardinal directions to within a few minutes of arc. Inside, a descending passage leads to an unfinished chamber cut deep in the bedrock, while an ascending passage and the tall Grand Gallery climb to the King’s Chamber, built of Aswan granite and roofed with nine granite beams. Above it are five low compartments, also roofed with granite, in which painted marks include Khufu’s name in a cartouche.

The pyramid was built by an organised Egyptian workforce, housed and fed in a town excavated at the foot of the plateau, with stone brought by boat from Tura and Aswan. Exactly how the blocks were raised is still debated. The sections below set out the evidence and the main proposals, each labelled by how well it is supported.

Source note: measurements follow W. M. F. Petrie’s survey (1883), read directly; height today, volume, the 3,700-year figure and the materials follow the Wikipedia article “Great Pyramid of Giza”; the workers’ town follows AERA.

  1. 1Original entrance and descending passageDocumented (surveyed)

    The original entrance on the north face, 17 m above the base and 7.3 m east of the centre line, opens into a passage that slopes down at 26½° for about 105 m, through the masonry and deep into the bedrock.

    Published: 1.06 m wide, 1.2 m high. Entrance 16.97 m above the pavement, 7.29 m east of the centre; slope 26°31′23″; 1.06 × 1.20 m in section (41.6 × 47.3 in). [1]

  2. Lower horizontal passageDocumented (surveyed)

    A short, low horizontal passage leads from the bottom of the descending passage into the subterranean chamber.

    Published: 8.79 m long. [1]

  3. 2Subterranean chamberDocumented (surveyed)

    A large chamber cut into the bedrock about 27 m below the base and never finished. Petrie described its floor as trenched by the cuttings made to dislodge blocks of rock, "an interesting specimen of quarrying".

    Published: 14.06 m long, 8.28 m wide. Walls 250.6 in W and 302.9 in E of the axis, 40 in and 366 in S of the centre; roof 1056 in below the pavement. The floor was never finished. [1]

    Note: The floor is irregular; the model shows it flat at about the lowest level.

  4. Blind passageApproximate

    A rough, narrow passage runs south from the subterranean chamber and stops after about 16 m, apparently a first working cut never enlarged.

    Published: 16.4 m long. Rough driftway ending 1012 in south of the centre. [1]

  5. 3Ascending passageDocumented (surveyed)

    Branching up from the descending passage, the ascending passage climbs at 26° for 39 m to the Grand Gallery. Its lower end is still blocked by granite plug blocks.

    Published: 39.29 m long. 1546.8 in on the slope at 26°2′30″; granite plugs fill about 15 ft (4.6 m) of its lower part. [1]

  6. 4Grand GalleryDocumented (surveyed)

    A tall, narrow hall 46.7 m long with a corbelled roof of seven overlapping courses on each side, continuing the slope of the ascending passage up to the level of the King's Chamber.

    Published: 46.68 m long, 2.06 m wide, 8.6 m high. From 1626.8 in N of the centre at 852.6 in up, to 61.7 in S at 1689 in up; corbelled roof, about 8.6 m high. [1]

    Note: The corbelled walls are drawn as a straight-sided prism.

    A level passage runs south from the foot of the Grand Gallery to the Queen's Chamber, with a step down in its floor near the chamber.

    Published: 38.73 m long. A step down in the floor 8.12 m north of the centre. [1]

  8. 6Queen's ChamberDocumented (surveyed)

    A gabled chamber with a niche in its east wall. Its ridge lies exactly on the pyramid's east–west centre line. The name "Queen's Chamber" is a modern convention.

    Published: 5.75 m long, 5.23 m wide, 6.21 m high. 226.47 × 205.85 in; walls 184.47 in high, 245.1 in to the ridge. The ridge lies exactly on the east–west centre plane of the pyramid. [1]

  9. 7Queen's Chamber north shaftApproximate

    A narrow shaft rises from the north wall. The Queen's Chamber shafts were found in 1872 by Waynman Dixon and explored in 1993 by Rudolf Gantenbrink's robot and in 2011 by the Djedi project.

    Note: Angle and length approximate.

  10. Queen's Chamber south shaftApproximate

    The south shaft is blocked by a small stone "door" reached by Rudolf Gantenbrink's robot in 1993; the Djedi project's camera looked behind it in 2011.

    Note: Angle and length approximate.

  11. 8AntechamberDocumented (surveyed)

    A small room between the Grand Gallery and the King's Chamber, usually interpreted as a portcullis chamber for sealing the burial.

    Published: 2.95 m long, 3.78 m high. From 113.7 in to 229.8 in S of the centre; floor 1692.6 in, roof 1841.5 in above the pavement. Width drawn approximately. [1]

    Note: The east–west width is approximate.

  12. 9King's ChamberDocumented (surveyed)

    Note: Position and size approximate.

  14. 10Relieving chambersApproximate

    Five low compartments stacked above the King's Chamber and roofed with granite beams. Four of the five were found by Howard Vyse in 1837. Painted marks in them include Khufu's name in a cartouche (Khnumu-Khufu), recorded by Petrie (§ 62).

    Note: Drawn as a single volume with a pointed top; the heights of the five compartments and the form of the top are approximate.

  15. 11King's Chamber north shaftApproximate

    Shafts from the north and south walls of the King's Chamber run out to the faces of the pyramid. Their purpose is debated.

    Note: Drawn as straight lines at approximate angles; their true courses are not reproduced.

  16. King's Chamber south shaftApproximate

    The south shaft of the King's Chamber, opening on the south face.

  17. 12Well shaftApproximate

    An irregular shaft from the foot of the Grand Gallery down to the descending passage, passing the "grotto", a natural cave in the limestone. One common explanation is that it let the workers who sealed the ascending passage get out; this is an interpretation, not established.

    Note: Course drawn approximately.

  18. 13Robbers' tunnel ("al-Ma'mun's tunnel")Approximate

    A tunnel forced through the north face, traditionally credited to the caliph al-Ma'mun (9th century), joins the ascending passage at its granite plugs. Visitors enter the pyramid through it today.

    Note: Course approximate.

  19. 14North Face Corridor (found 2023)Approximate

    A corridor-shaped space just behind the great chevron blocks above the entrance, characterised by muon imaging in 2023. Its purpose is not known.

    Published: 9.06 m long, 2.02 m wide, 2.18 m high. Muon imaging: floor about 20 m above ground, centred on the chevron, just behind it; it stops at the south end. [4]

    Note: Drawn as a 9 × 2 × 2 m box; position approximate.

  20. 15The "Big Void" (detected 2017)Uncertain (detected, not established)

    A large empty space above the Grand Gallery, detected by muon imaging and announced in 2017. Its shape, exact position and purpose are unknown.

    Published: 30 m long. At least 30 m long, with a cross-section similar to that of the Grand Gallery (Morishima et al. 2017, as reported by the reference work). [5]

    Note: Drawn only to show that something is there. Its exact position, inclination and form have not been established.

Sources for this reconstruction

The exterior and the positions of the main passages and chambers follow W. M. F. Petrie's survey (1883), read directly and converted from inches to metres, measured from the centre of the base. The shafts, relieving chambers, well shaft and robbers' tunnel are placed by us from published descriptions (the Wikipedia article listed below, not a survey) and are approximate; the voids found by muon imaging are uncertain, as marked. Their angles, lengths and courses are reconstruction assumptions.

  • Shaft angles and lengths, the relieving chambers (drawn as one volume), the well shaft, the robbers' tunnel and the widths of some passages are our approximations from written descriptions, not survey data.
  • The Big Void is drawn only to show that something is there; its form, position and inclination are unknown. The North Face Corridor is drawn as a 9 × 2 × 2 m box.
  • The "as built" casing and the stepped core "today" are drawn to the published outline; individual courses and blocks are not modelled. The summit today is shown flat at 138.5 m.
  • Views marked "Interpretation" show construction proposals, drawn schematically by us; none is evidence of how the pyramid was built.

The pyramid is built mainly of local Giza limestone, around an internal hillock of rock. The outer casing was white limestone brought by boat from Tura, and granite blocks of up to about 80 tonnes came from Aswan for the King's Chamber. Most of the casing was later removed; a limited number of casing stones remain in place at the base. Wikipedia, Great Pyramid of Giza; Wikipedia, Giza pyramid complex The King's Chamber is roofed with nine granite beams. Above it are five low compartments roofed with granite beams, four of them found by Howard Vyse in 1837; painted marks in them include Khufu's name in a cartouche.

The big question

How was it built?

No ancient text describes how the pyramids were raised, but quarries, papyri, the workers' town and experiments narrow the possibilities. Each proposal below is labelled by how well the evidence supports it.

  • Well-supported evidencePhysical remains, inscriptions or measurements that archaeologists agree on.
  • Plausible reconstructionConsistent with the evidence and widely accepted, but not directly proven.
  • Active scholarly debateProposed by specialists; the evidence is partial or points in different directions.
  • Speculative or weakly supportedContradicted by, or lacking, archaeological evidence. Mentioned so readers can place it.

The building sequence

  1. Step 1

    Level and lay out

    Well-supported evidence

    The base was laid out around a hillock of rock left inside the core, squared and aligned to north. Wikipedia, Great Pyramid of Giza; Petrie

  2. Step 2

    Quarry

    Well-supported evidence

    Core blocks were local Giza limestone; casing limestone came from Tura and granite from Aswan. Wikipedia, Great Pyramid of Giza

  3. Step 3

    Transport

    Well-supported evidence

    Tura limestone and Aswan granite came by boat, through Nile waterways to the foot of the plateau; on land, probably by sledge. Wikipedia, Great Pyramid of Giza; Sheisha et al.; Wikipedia, Diary of Merer; Fall et al.

  4. Step 4

    Raise

    Active scholarly debate

    Ramps of some form, perhaps with levering for the last lifts. The exact system is debated. Wikipedia, Construction of the Egyptian pyramids

  5. Step 5

    Set and fit

    Plausible reconstruction

    Blocks were set in horizontal courses, bound with mortar. Wikipedia, Great Pyramid of Giza; Petrie

  6. Step 6

    Dress the faces

    Active scholarly debate

    One proposal is that the casing faces were smoothed from the top down as the working ramps were removed. This is an assumption, not attested.

Ramp proposals compared

long ramp

Straight ramp

Active scholarly debate

One ramp against a face. Practical low down; to reach the top at 1:10 it would be about 1.5 km long.

Zigzag ramp

Active scholarly debate

Switchbacks up one face. Short, but faces grow narrow near the top.

Spiral ramp

Active scholarly debate

Wraps around all faces at a steady gradient, but hides the corners surveyors relied on.

external ramp, lowest ~30%

Internal ramp

Speculative or weakly supported

Outside for about the lowest 30%, then just inside the faces (after Houdin, 2006). Unproven.

Reconstruction note: schematic comparison drawn by us, not to scale; gradients and turns are illustrative. Purple marks the proposed ramp. No ramp of any of these forms has been found at the Great Pyramid; each is a proposal (see the sources for each under "The main proposals" below).

The 3D model above can show each ramp proposal on the pyramid: choose a view under "Construction interpretations".

The main proposals and the evidence for them

Local quarries, Tura limestone and Aswan granite

Well-supported evidence

Most of the pyramid is local limestone from the Giza plateau. Fine white limestone for the casing came from Tura across the river, and granite for the King's Chamber from Aswan.

What supports it

  • Reference works describe the core as mainly local plateau limestone, with Tura limestone and Aswan granite brought by boat.
  • The papyri of the inspector Merer, dated to year 26–27 of Khufu, record his crew shipping limestone from the Tura quarries to Giza.
  • Petrie recorded saw marks and a tube-drill hole on the granite coffer in the King's Chamber.

Problems and open questions

  • The core also contains a natural rock outcrop; how much of the volume it takes up is not precisely known.

Sources: Wikipedia, Great Pyramid of Giza; Wikipedia, Diary of Merer; Petrie; Tallet*

Boats, waterways and sledges

Well-supported evidence

Heavy stone travelled by boat on the Nile and on waterways reaching the foot of the plateau, then on sledges.

What supports it

  • Merer's logbook records voyages from Tura to Giza, stopping at a basin called She-Khufu; Tallet identifies a harbour at Giza, Ro-She-Khufu, as the destination of the casing stones.
  • Sediment cores show that a branch of the Nile stood at high water beside Giza in the reigns of Khufu, Khafre and Menkaure (Sheisha et al. 2022).
  • A Middle Kingdom painting in the tomb of Djehutihotep (about 1880 BCE) shows water poured in front of a sledge carrying a colossus; laboratory tests show that damp sand can greatly reduce the pull needed (Fall et al. 2014).

Problems and open questions

  • The layout of the harbours and canals at Giza is still being investigated.

Sources: Wikipedia, Diary of Merer; Sheisha et al.; Fall et al.; Tallet*

An organised, fed and housed workforce

Well-supported evidence

The pyramids were built by organised crews supported by bakers, brewers and administrators, who lived in a town at the foot of the plateau. Crews were organised in named gangs and smaller divisions.

What supports it

  • The excavated town of Heit el-Ghurab, south-east of the plateau beyond a large stone wall, with bakeries, kitchens, workshops and large quantities of animal bone.
  • A cemetery of workers and overseers nearby, with skeletons showing healed injuries.
  • Merer's crew is recorded as a phyle (a work unit) in his logbook.

Problems and open questions

  • The size of the workforce is an estimate. Figures in the literature range from a low calculation of about 2,000 builders to a construction-management study (with Mark Lehner) of about 14,500 on average and 40,000 at the peak.

Sources: Ancient Egypt Research Associates (AERA); Egyptian Ministry of Tourism and Antiquities; Wikipedia, Giza pyramid complex; Lehner; Wikipedia, Construction of the Egyptian pyramids; Wikipedia, Diary of Merer

A straight ramp

Active scholarly debate

One long ramp built against a face and raised as the pyramid rose.

What supports it

  • Remains of small construction ramps and inclined causeways have been found at Giza and at other pyramids.
  • A ramp works well for the lower courses, where most of the volume lies.

Problems and open questions

  • At a gradient of 1:10 it would need to be about 1.5 km long to reach the top (146.7 m × 10).
  • As a way to build the whole pyramid it is widely rejected: it would be enormous and costly, and no such ramp has been found.

Sources: Wikipedia, Construction of the Egyptian pyramids

Zigzag or switchback ramps

Active scholarly debate

Ramps climbing a face in legs, turning back on landings.

What supports it

  • Proposed to keep the ramps shorter and smaller.
  • At the Hatnub quarry, a ramp flanked by stairs with post holes, dating at least to Khufu's reign, was used to haul blocks up slopes of 20 per cent or more.

Problems and open questions

  • The faces become shorter as the pyramid rises, leaving less room for ramps and for turning blocks.

Sources: Wikipedia, Construction of the Egyptian pyramids; University of Liverpool and IFAO (Y. Gourdon

A ramp wrapping around the pyramid

Active scholarly debate

A ramp spiralling around the faces. Mark Lehner has suggested a spiral ramp starting in the quarry to the south-east.

What supports it

  • Keeps a steady gradient all the way up.

Problems and open questions

  • It would cover the building for years and hide the corners and edges that builders needed to keep the pyramid true.

Sources: Wikipedia, Construction of the Egyptian pyramids; Lehner*

Levering and lifting devices

Active scholarly debate

Blocks raised step by step with levers, probably together with ramps. Levering is widely considered the most likely complement to ramps.

What supports it

  • Herodotus, writing in the 5th century BCE, says the stones were raised from tier to tier with levers made of short timbers.
  • Experiments (for example by Martin Isler for NOVA in 1992) have raised blocks one course at a time with levers and shims.
  • Lehner has suggested levers for the small volume of stone near the top, where ramps are least practical.

Problems and open questions

  • Herodotus wrote about 2,000 years after the pyramid was built.
  • Raising the King's Chamber granite, with blocks reported at up to about 80 tonnes, remains hard to explain.

Sources: Wikipedia, Construction of the Egyptian pyramids; Wikipedia, Great Pyramid of Giza; Herodotus*

An internal ramp

Speculative or weakly supported

The architect Jean-Pierre Houdin proposes an external ramp for roughly the lowest 30 per cent of the height, and above it a ramp spiralling inside the pyramid, just behind the faces.

What supports it

  • Would explain the absence of large external ramps.
  • Houdin points to a notch near one corner of the pyramid as a possible opening.

Problems and open questions

  • The hypothesis remains unproven.
  • Egyptologists including David Jeffreys and John Baines have criticised it as far-fetched or too narrowly focused on one pyramid.

Sources: Wikipedia, Construction of the Egyptian pyramids; Houdin*

Blocks cast from limestone concrete

Speculative or weakly supported

The chemist Joseph Davidovits proposes that most blocks were cast in moulds from a limestone slurry rather than cut.

What supports it

  • A 2006 materials-science study (M. Barsoum and colleagues) reported microstructures it argued were man-made.

Problems and open questions

  • The idea is not accepted by the academic mainstream; a petrographic study (D. Jana, 2007) rejected a man-made origin.
  • It does not explain the large granite blocks, which Davidovits agrees were carved.

Sources: Wikipedia, Joseph Davidovits

Moving stone over sand

Sledge on dry and damp sandOn dry sand a heap of sand builds up in front of the sledge and resists it. On damp sand, water bridges between the grains stiffen the surface, so no heap forms and the pulling force is much lower.Dry sandheap of sand pushed aheadhigh pullDamp sandwater poured aheadlower pull
Well-supported evidenceIn laboratory tests, the right amount of water made sand stiff enough that no heap formed in front of a model sledge, and the pulling force fell by about half; too much water made it worse again. A Middle Kingdom painting in the tomb of Djehutihotep shows water poured in front of a sledge carrying a colossal statue. Fall et al.; Wikipedia, Construction of the Egyptian pyramidsPlausible reconstruction That the Giza builders wetted sand this way is an inference; it is not recorded at Giza. The diagram is schematic.

Aligning the pyramid

The base and true northTrue northError exaggerated about 50×Star method: a plumb line and two starsstar Astar BWhen both stars line up on a plumb lineSun method: the tip of a shadow on the equinoxShadow tips mark an east–west line
Well-supported evidence Petrie measured the sides as turned on average only about 3′43″ (under a tenth of a degree) from true north. PetrieActive scholarly debate How it was done is debated. Kate Spence proposed using the simultaneous transit of two stars across a plumb line, which would also explain the small errors (2000). Glen Dash proposed marking the tips of a gnomon's shadow around the equinox (2017). Spence; Dash* The diagrams are schematic; the stars are not drawn in their real positions.
Weighing it up

What the evidence shows

What remains debated

Claims that the pyramid was built by a lost civilisation or with unknown technology are not supported by any archaeological evidence. The workers' town and cemetery, Khufu's name painted in the relieving chambers and Merer's papyri all tie the monument to Khufu's Egypt.
