Most visitors to Saqqara never go underground. The Step Pyramid draws the crowds and the painted mastabas draw the cameras, while a plain modern entrance nearby leads down into a corridor that many tour groups skip. At the bottom stand granite boxes so large that visitors instinctively lower their voices. Each was made to hold the mummified body of a single bull.
This was not simple animal burial. The Apis bull was treated in life as the living manifestation of the god Ptah, kept in a temple with its own staff, and mourned at death with an elaborate funeral. The underground galleries built to receive it, known today as the Serapeum, are among the most unusual building projects in ancient Egypt, and the site was lost to history until a French archaeologist followed a half-buried sphinx in 1850.
What was the Apis bull and why was it buried here?
The Apis cult centered on Memphis, the ancient capital a short distance from Saqqara, and it was already old when the great pyramids were built. Egyptians believed that Ptah, the city's creator god and patron of craftsmen, was manifested on earth in a living bull. Priests looked for a calf with specific markings: a black hide, a white triangle on the forehead, a vulture-like mark on the back, a crescent on the flank, and double hairs in the tail. A calf that matched was installed in a temple at Memphis, consulted as an oracle, and paraded on festival days.
When the bull died, it was embalmed and became linked with Osiris, lord of the dead; the Greeks later fused the two names into Osorapis, or Serapis. The mummy was carried from Memphis to Saqqara in a formal procession and sealed in a vault, while priests began the search for the next calf. Accounts of the mourning period speak of several weeks of ritual, but the exact length varied and is better documented for later periods.
How was the Serapeum rediscovered?
By the early 1800s the location of the Serapeum had been forgotten. The Greek geographer Strabo, who visited Egypt around 24 BCE, had described a temple of Serapis in sandy ground, approached by an avenue of sphinxes partly buried by drifting sand. In 1850 the French scholar Auguste Mariette, officially in Egypt to acquire manuscripts for the Louvre, saw the head of a sphinx emerging from the sand at Saqqara and recognized it from Strabo's description. He abandoned his original assignment and began to dig.
Following the avenue of sphinxes, Mariette's workmen reached the entrance of the galleries in 1851. Inside he found long corridors cut into the rock, lined with side chambers holding huge stone sarcophagi, along with thousands of stelae and votive objects left by ancient visitors. Most Apis burials had been plundered in antiquity, but Mariette reported a small number of undisturbed burials, a rare survival. Claims that a single complete, untouched Apis mummy was found are repeated widely but are not well supported, so treat them with caution. Many of the finds went to the Louvre.
Visit Saqqara With a Guide
The Serapeum is easy to walk through without understanding it. These Egypt Sun Travel tours combine Saqqara with Giza and Memphis, with a licensed Egyptologist and a private air-conditioned vehicle; ask us whether the Serapeum is open on your date.
Who built the galleries, and how heavy are the sarcophagi?
The earliest Apis burials here date to the reign of Amenhotep III (Eighteenth Dynasty, 14th century BCE), in separate tombs rather than a shared gallery. The decisive step came under Ramesses II, when his son Khaemwaset, high priest of Ptah at Memphis and a famous restorer of older monuments, had a long underground gallery cut into the rock. Today this is called the Lesser Vaults. Later kings extended the complex, and the Greater Vaults, begun under Psamtik I in the Twenty-Sixth Dynasty, hold the 24 great sarcophagi seen today, dating from about 550 BCE through the Ptolemaic period and into the Roman era.
Each sarcophagus was made as a hollowed box with a separate lid, mostly in granite and some in other hard stone. A well-known set of measurements puts one box at about 3.85 m long, 2.3 m wide and 2.3 m high. The box weighs roughly 40 tonnes and the lid about half that, so a complete sarcophagus is on the order of 60 tonnes; much larger figures sometimes quoted online are not backed by measurement. Inscriptions suggest well over sixty Apis bulls were buried at Saqqara across about thirteen centuries, though only some burials survive as sarcophagi.
Were the sarcophagi really machine-polished?
Their smooth, almost mirror-like surfaces and sharp corners are sometimes presented online as proof of lost technology. The evidence points elsewhere. Egyptian stoneworkers had copper tools, pounding stones of harder rock such as dolerite, wooden sledges, ramps, ropes and abundant labor, and they finished hard stone by abrasion, rubbing it with quartz sand and water and then polishing. Tool marks and unfinished surfaces occur at Aswan and elsewhere, and some Serapeum sarcophagi were inscribed only by scratching, which shows they were not all finished to the same level.
The effort was still enormous. A stela from the reign of Ptolemy II (around 247 BCE) is reported to record about 28 working days to bring one sarcophagus and its lid to the Serapeum, a figure that fits the scale of the transport from Aswan by river and then overland. The achievement is real, and it needs no mystery to explain it.
Why does the Serapeum matter beyond the bulls?
The Serapeum was a functioning institution with priests, endowments and records, used from the New Kingdom into the Greco-Roman period, which makes it one of the longest-lived burial sites in Egypt. The stelae from its chapels, many now in the Louvre, record temple administration, royal visits and private devotion that royal monuments rarely mention. The cult also shows that sacred animal worship was an organized part of state religion for over a thousand years. A wider animal necropolis lies nearby, with galleries of ibises, baboons and other animals; the story of Imhotep's later cult and the ibis galleries explains how those tie into Saqqara's wider history.
How can you visit the Serapeum today?
The Serapeum sits within the Saqqara archaeological zone, a short drive or walk from the Step Pyramid enclosure. It has usually required its own ticket from the general Saqqara admission, and access has been limited at times for conservation, so confirm on the day. Inside, the corridor slopes down into cool, dim galleries lit by artificial light; the scale of the sarcophagi becomes clear only when you stand beside one. Bring a small torch, shoes with grip and water for the plateau, and read a little about the Apis cult first, since little on site explains it at length.
It combines easily with the Step Pyramid and the painted tombs of Saqqara, and many day trips continue to Memphis or to the Pyramids of Giza. A guide helps here more than at most Saqqara sites, because the galleries are easy to walk through without grasping what they were for.
Frequently Asked Questions
Can you go inside the Serapeum of Saqqara?
Usually yes, by a sloping tunnel into the Greater Vaults, but access has sometimes been closed or restricted for conservation. It normally needs its own ticket, so check at the Saqqara ticket office before you go. It is not suitable for people who struggle with enclosed or dim spaces.
How heavy are the Serapeum sarcophagi?
A commonly cited measurement is a box of about 40 tonnes with a lid of about half that, so roughly 60 tonnes complete. Figures of 70 to 100 tonnes or more circulate online but are not well supported. All are made of hard stone, mostly granite, and were moved from Aswan.
Are there mummies in the Serapeum?
No. The sarcophagi seen today are empty, because most burials were robbed or disturbed in antiquity. Mariette reported a few undisturbed burials in 1851, but claims of a single perfectly intact Apis mummy are not reliable.
Who was Khaemwaset?
Khaemwaset was a son of Ramesses II, high priest of Ptah at Memphis, and well known for restoring older monuments. He is credited with creating the Lesser Vaults, the first long gallery for Apis burials at Saqqara.
Does the Serapeum prove ancient technology we have lost?
No. The finish of the sarcophagi is consistent with copper tools, harder pounding stones, abrasive sand and a large workforce. A Ptolemaic-era stela reportedly records the transport of one sarcophagus as taking 28 working days.
