[1] Many historians believe that the third dynasty played an important role in the transition from Early Dynastic Period of Egypt to the Age of the Pyramids.

[3] The Buried Pyramid was a previously unknown structure until, in 1951, Egyptologist Zakaria Goneim noticed the odd rectangular shape in the desert while excavating the nearby Unas complex.

During the next stage of excavation, Goneim discovered a descending passage to the north side which led to a gallery blocked with rubble and masonry.

[6] Criticism of Goneim and his subsequent apparent suicide on January 12, 1959, dampened the interest in the pyramid and investigation was left incomplete.

In 1963, the excavation was re-opened by Jean-Philippe Lauer due to the possibility of a south tomb and his desire to find the missing mummy.

While the name itself contains no titles and thus it is uncertain if this is the same architect that planned Djoser's Step Pyramid, the line of succession and similar architectural features suggest such a possibility.

The pyramid's foundations stand upon an uneven rock surface, leading the builders to try to level the terrain by building terraces, some reaching ten metres high.

[10] The entrance to the subterranean structure lies to the north, starting with a narrow passage that descends for about 61 m (200 ft) until meeting a vertical shaft from the top of the corridor.

The sarcophagus is cut from a single block of fine alabaster; its lid was vertical, slid into place and held at the front face by means of mortar sealing.

[14] In the substructure of the mastaba, following a passage accessed by a vertical shaft, the excavators unearthed a chamber where they found a wooden coffin with the remains of an unidentified two-year-old child.
