An interpretive archaeological exhibit

Khufu:
Beneath the Stone

Walk the Giza Plateau, enter a scale-led Great Pyramid, and descend into a disputed scan reconstruction.

The deep SAR spaces are disputed interpretations. Documented Khufu chambers remain unpainted.

A monument between evidence and imagination

Documented architecture anchors the visit. The historical landscape is an evidence-led Nile floodplain mosaic. Muon scans reveal real density anomalies; the deeper SAR descent remains explicitly disputed.

Connectivity and sound-path method

A clearance-aware portal graph validates every authored room, passage junction, doorway, floor transition, and six-foot visitor route. Petrie's survey table anchors the approximately 0.52 m final floor step in the Queen's Passage. The optional 63–1000 Hz sound display uses a first-order image-source approximation for early reflections. It is an interpretive geometry aid, not evidence that Khufu's builders designed an acoustic machine. A published 2.3 Hz Queen's Chamber result is an ambient structural-vibration measurement and is deliberately not reproduced by the ray model.

Documented architecture

Scale and known rooms follow published surveys and Egypt's Ministry of Tourism and Antiquities. Present shells stop at their surviving heights: Khufu 138.5 m, Khafre 136.4 m, and Menkaure about 61 m. Khafre retains its connected upper Tura-limestone casing. Menkaure's present mode retains a photo-calibrated seven-course granite remnant; its reconstructed original casing uses the documented Aswan-granite lower quarter and limestone above.

Peer-reviewed scan features

The Big Void and North Face Corridor are represented as unexcavated spaces detected through cosmic-ray muons.

Interpretive SAR reconstruction

The deep chamber network follows Biondi and Malanga's proposed topology. It has not been archaeologically verified and remains disputed.

Interior reconstruction

Each generated plate is grounded in a space-specific documentary photograph. Modern rails, tourists, flash, and labels were removed; no decoration was added to documented Khufu chambers.

Hieroglyphs and inscription policy

The accessible Giza royal-pyramid interiors had no formal Pyramid Text program. Red marks in the construction chambers above Khufu's King's Chamber are builders' quarry and work-gang marks, not decorative wallpaper. The catalog transcription Ḫwfw uses Gardiner signs Aa1 · G43 · I9 · G43; it is a normalized reading, not a facsimile. On Met 22.1.25, “Horizon of Khufu” is a bracketed scholarly restoration of a damaged building inscription. Missing signs are never AI-completed for display.

Terrain and surrounding complexes

Present topography is a local WGS84 crop of USGS/NASA SRTMGL1. Pyramid radar returns are removed only inside engineered foundations. Temples, causeways, subsidiary pyramids, boat pits, cemeteries, the Sphinx, and workers' precinct follow the Harvard Digital Giza inventory; lost fabric is labeled interpretive.

Historical landscape

Heyday mode reconstructs the active Khufu Nile branch as a wetland, cultivated floodplain, and riparian mosaic—not a tropical rainforest. The sediment-core study groups pollen as helophytes, sedges, date-palm/willow, cereals, tropical Nilotic taxa, upland herbs, and ferns. Those groups support the broad ecology; exact plants, density, shoreline, canals, and field boundaries remain interpretive.
