The Pyramid of Djoseris an archaeological site in the Saqqara necropolis, Egypt, northwest of the city of Memphis. The 6-tier, 4-sided structure is the earliest colossal stone building in Egypt. It was built in the 27th century BC during the Third Dynasty for the burial of Pharaoh Djoser. The pyramid is the central feature of a vast mortuary complex in an enormous courtyard surrounded by ceremonial structures and decoration.

The pyramid went through several revisions and redevelopments of the original plan. The pyramid originally stood 62.5 metres (205 ft) tall, with a base of 109 m × 121 m (358 ft × 397 ft) and was clad in polished white limestone. The step pyramid (or proto-pyramid) is considered to be the earliest large-scale cut stone construction made by man, although the nearby enclosure wall "Gisr el-Mudir" is suggested by some Egyptologists to predate the complex, and the South American pyramids at Caral are contemporary.

In March 2020, the pyramid was reopened for visitors after a 14-year restoration.

Djoser was the first or second king of the 3rd Dynasty (c. 2670–2650 BC) of the Egyptian Old Kingdom (c. 2686–2125 BC). He is believed to have ruled for 19 years or, if the 19 years were biennial taxation years, 38 years. He reigned long enough to allow the grandiose plan for his pyramid to be realized in his lifetime.

Djoser is best known for his innovative tomb, which dominates the Saqqara landscape. In this tomb he is referred to by his Horus name Netjerikhet; Djoser is a name given by New Kingdom visitors thousands of years later. Djoser's step pyramid is astounding in its departure from previous architecture. It sets several important precedents, perhaps the most important of which is its status as the first monumental structure made of stone.

The social implications of such a large and carefully sculpted stone structure are staggering. The process of building such a structure would be far more labor-intensive than previous monuments of mud-brick. This suggests that the state, and therefore the royal government had a new level of control of resources, both material and human. Also, from this point on, kings of the Old Kingdom are buried in the North, rather than at Abydos.

Although the plan of Djoser's pyramid complex is different from later complexes, many elements persist and the step pyramid sets the stage for later pyramids of the 4th, 5th, and 6th Dynasties, including the great pyramids of Giza. Though the Dynastic Egyptians themselves did not credit him as such, most Egyptologists attribute Djoser's vizier Imhotep with the design and construction of the complex.

Precedents

Djoser's Pyramid draws ideas from several precedents. The most relevant precedent is found at Saqqara mastaba 3038 (c. 2700 BC). The substructure lay in a 4 m (13 ft) deep rectangular pit, and had mudbrick walls rising to 6 m (20 ft). Three sides were extended and built out to create eight shallow steps rising at an angle of 49°. This would have been an elongated step pyramid if the remaining side had not been left uncovered. In another parallel to Djoser's complex, to complete this mastaba complex a niched enclosure wall was erected.

Imhotep used royal cubits in its design.

The Step Pyramid

The superstructure of the Step Pyramid is six steps and was built in six stages, as might be expected with an experimental structure. The pyramid began as a square mastaba-like structure (M1) which was gradually enlarged, first evenly on all four sides (M2) and later just on the east side (M3). The mastaba was built up in two stages, first to form a four-stepped structure (P1) and then to form a six-stepped structure (P2), which now had a rectangular base on an east–west axis. The fact that the initial mastaba was square has led many to believe that the monument was never meant to be a mastaba, as no other known mastabas had ever been square. When the builders began to transform the mastaba into the four-step pyramid, they made a major shift in construction. Like in the construction of the mastaba, they built a crude core of rough stones and then chased them in fine limestone with packing in between. The major difference is that in mastaba construction they laid horizontal courses, but for the pyramid layers, they built in vertical accretion layers that leaned inwards, while using blocks that were both bigger and higher quality. Much of the rock for the pyramid was likely quarried from the construction of the great trench. It is widely accepted that ramps would have been used to raise heavy stone to construct the pyramid, and many plausible models have been suggested. For transport, apparatuses like rollers were used in which the heavy stone could be placed and then rolled.

The Substructure

Under the step pyramid is a labyrinth of tunneled chambers and galleries that total nearly 6 km in length and connect to a central shaft 7 m square and 28 m deep.These spaces provide room for the king's burial, the burial of family members, and the storage of goods and offerings. The entrance to the 28 m shaft was built on the north side of the pyramid, a trend that would remain throughout the Old Kingdom. The sides of the underground passages are limestone inlaid with blue faience tile to replicate reed matting. These "palace façade" walls are further decorated by panels decorated in low relief that show the king participating in the Heb-sed. Together these chambers constitute the funerary apartment that mimicked the palace and would serve as the living place of the royal ka. On the east side of the pyramid, eleven shafts 32 m deep were constructed and annexed to horizontal tunnels for the royal harem. (The existence of this "harem" is debated.) These were incorporated into the pre-existing substructure as it expanded eastward. In the storerooms along here over 40,000 stone vessels were found, many of which predate Djoser. These would have served Djoser's visceral needs in the afterlife. An extensive network of underground galleries was located to the north, west and south of the central burial chamber and crude horizontal magazines were carved into these.

The Burial Chamber

The burial chamber was a vault constructed of four courses of well-dressed granite. It had one opening, which was sealed with a 3.5 ton block after the burial. Nobody was recovered as the tomb had been extensively robbed. Lauer believes that a burial chamber of alabaster existed before the one of granite. He found interesting evidence of limestone blocks with five pointed stars in low relief that were likely on the ceiling, indicating the first occurrence of what would become a tradition. The king sought to associate himself with the eternal North Stars that never set so as to ensure his rebirth and eternity.

Djoser's Step Pyramid complex included several structures pivotal to its function in both life and the afterlife. A pyramid was not simply a grave in ancient Egypt. Its purpose was to facilitate a successful afterlife for the king so that he could be eternally reborn. The symbolism of the step pyramid form, which did not survive beyond the 3rd Dynasty, is unknown, but it has been suggested that it may be a monumental symbol of the crown, especially the royal mortuary cult, since seven small step pyramids (that were not tombs) were built in the provinces. Another well accepted theory is that it facilitated the king's ascension to join the eternal North Star.

The main modern excavator of the Step Pyramid was Jean-Philippe Lauer, a French architect who reconstructed key portions of the complex. The complex covers 15 ha (37 acres) and is about 2.5 times as large as the Old Kingdom town of Hierakonpolis. Several features of the complex differ from those of later Old Kingdom pyramids. The pyramid temple is situated at the north side of the pyramid, whereas in later pyramids it is on the east side. Also, the Djoser complex is built on a north–south axis, whereas later complexes utilize an east–west axis. Furthermore, the Djoser complex has one niched enclosure wall, whereas later pyramids have two enclosure walls with the outside one being smooth and the inside one sometimes niched.
