The Egyptian pyramids contained burial chambers, stone sarcophagi, and narrow passageways designed to protect and house the pharaoh’s body for eternity. But the specifics vary dramatically depending on which pyramid you’re talking about. The Great Pyramid of Giza, the most famous of all, has a surprisingly spare interior: no treasure, no decorations, and no mummy. Other pyramids, particularly the later ones at Saqqara, were covered floor to ceiling with thousands of hieroglyphs. Here’s what we actually know about what’s inside.
Inside the Great Pyramid of Giza
The Great Pyramid, built for the pharaoh Khufu around 2560 BCE, contains three main chambers connected by a series of tight corridors. The lowest is the subterranean chamber, carved into the bedrock beneath the pyramid. It was never finished. Rough-cut and irregular, it appears the builders abandoned this room partway through construction and moved the burial site higher up into the pyramid’s body. Egyptologists sometimes call it “the Pit.”
Above it, roughly in the center of the pyramid, sits the Queen’s Chamber (a misleading name, since no queen was buried there). Higher still is the King’s Chamber, the true burial room, where the only object of significance remains to this day: an enormous granite sarcophagus set into the floor. It’s empty. No mummy, no treasure, no lid. Napoleon reportedly spent a night in this chamber, and he would have found it just as bare as visitors do now. The sarcophagus once held Khufu’s mummified body, but it was likely looted thousands of years ago.
What makes the Great Pyramid’s interior remarkable isn’t what’s in it but how it was built. The passage leading to the King’s Chamber runs through the Grand Gallery, one of the most impressive architectural spaces in the ancient world. It stretches 46.7 meters (153 feet) long and rises 8.6 meters (28 feet) high, built from fine white Tura limestone laid in seven corbelled courses. Each layer of stone projects inward by about 7.6 centimeters, gradually narrowing the space from 2.1 meters wide at the base to less than a meter at the top, where a flat strip of stone caps the ceiling. Walking through it feels like standing inside a giant stone funnel tilted at a steep angle.
One notable absence: the walls of the Great Pyramid are completely bare. No paintings, no carvings, no hieroglyphs. For the most famous monument in human history, the interior is strikingly empty.
Pyramids With Writing on the Walls
The pyramids at Saqqara tell a very different story. Starting with the pyramid of Unas, the last pharaoh of the Fifth Dynasty (around 2350 BCE), builders began covering interior walls with thousands of hieroglyphs known as the Pyramid Texts. These are the oldest religious writings in ancient Egypt, and they served a specific purpose: spells and instructions to help the dead king navigate the afterlife.
Inside Unas’ pyramid, nearly every wall surface in the antechamber, burial chamber, and connecting passageway is covered with vertical columns of hieroglyphs. The only exception is the area immediately around the sarcophagus, which was lined with alabaster and painted to look like reed mats inside a wooden frame, recreating the appearance of a royal dwelling. The contrast is striking: sacred text everywhere, and then a cozy domestic illusion surrounding the body itself.
The tradition continued through the Sixth Dynasty. Pyramid Texts have been found in the tombs of the pharaohs Teti, Pepi I, Merenre I, and Pepi II, as well as three of Pepi II’s queens. In total, inscribed texts have been identified in at least eleven pyramids at Saqqara, spanning roughly 200 years. These pyramids give us something the Great Pyramid never did: a window into what the Egyptians believed was happening to the king after death.
What Looters Took
Nearly every pyramid was robbed in antiquity, most within a few centuries of being sealed. The treasures originally placed inside would have been extensive. Based on what we know from intact tombs like Tutankhamun’s (which was a modest tomb by pharaonic standards, not a pyramid), royal burials included gold jewelry, furniture, weapons, food offerings, canopic jars holding preserved organs, and elaborate gilded coffins. For a pharaoh powerful enough to build a pyramid, the grave goods would have been extraordinary.
None of it survived. By the time modern explorers entered the pyramids, the chambers were empty or contained only the stone sarcophagi, which were too heavy to move. In some cases, even the mummies were gone. The Great Pyramid’s sarcophagus sits open and empty with no trace of Khufu’s remains.
Hidden Spaces Still Being Found
The pyramids haven’t given up all their secrets. In 2017, physicists using muography (a technique that tracks subatomic particles called muons as they pass through stone) detected a large void above the Grand Gallery in the Great Pyramid. It’s estimated to be about 30 meters long and several meters high. No one has entered it, and its purpose remains unknown. Some researchers believe it could be connected to a still-undiscovered burial chamber for Khufu.
In 2023, the same ScanPyramids research team confirmed another hidden space: a corridor behind the chevron-shaped stone blocks on the pyramid’s north face. Called the North Face Corridor, it had been sealed and hidden for 4,500 years. Researchers used a combination of ground-penetrating radar, ultrasonic tomography, and electrical resistivity to map it without drilling into the stone.
Even the ground around the pyramids holds surprises. Recent scans near the Great Pyramid revealed an L-shaped underground structure that doesn’t match any natural geological formation. Researchers aren’t sure whether it’s empty or filled with sand and gravel, but its deliberate shape suggests it was built by human hands. It hasn’t been excavated yet.
Why the Interiors Vary So Much
The pyramids were built over a span of roughly a thousand years, and construction practices changed significantly. The earliest pyramids, like Djoser’s step pyramid at Saqqara (around 2670 BCE), had relatively simple underground burial vaults. The Great Pyramid represented a peak in engineering ambition, with its internal chambers lifted high into the structure itself rather than buried underground. Later pyramids grew smaller and less structurally complex, but their interiors became richer with text and decoration.
By the end of the pyramid-building era, the monuments were more modest in scale, but the walls carried increasingly elaborate funerary literature. The shift suggests that over time, the Egyptians placed less emphasis on the sheer mass of stone protecting the body and more on the magical texts they believed would protect the soul. The pyramids, in other words, evolved from fortresses of stone into libraries for the dead.
