The layer pyramid: https://en.wikipedia.org/wiki/Layer_Pyramid
This seems to have similar structure to the pyramid at saqqare of sekhemet.
The Buried Pyramid (https://en.wikipedia.org/wiki/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. Criticism of Goneim and his subsequent suicide on January 12, 1959 dampened the interest in the pyramid and investigation was left incomplete.
That pyramid may be visited, but the public is not allowed access to the base and substructures.
There is something else interesting about this. Besides the archeologist excavating this particular pyramid committed suicide and its similar setup to the southern pyramid a zawyat el aryan, it also links to what egyptologist call the most ancient structure known in egypt.

A good writeup is here:
Quote: During Barsanti’s excavations, archaeologists were puzzled when the trench filled with rainwater which very quickly drained to about a metre deep, suggesting that there may have been an undiscovered passage or chamber beneath the trench. Unfortunately the structure has never been further investigated because of its inaccessibility in the military zone.
The Northern pyramid
Large blocks of limestone and granite lie on the floor of the trench and may have been intended for use in the burial chamber. At the bottom of the trench there was a huge oval pink granite sarcophagus, which may or may not belong to the structure.
Significantly, Petrie found fragments of a similar styled sarcophagus while excavating Djedefre’s complex at Abu Rawash. (The revised edition of Petrie, The Pyramids and temples of Gizeh, p. 54.)
The deep T- shaped shafts are of interest to me, placing a sarcophagus deep under ground level.
The knobs we see on the lid of the sarcophagus are seen elsewhere as indicated above, for one Menkaur pyramid’s casing stones. What is fantastic is how the rough stones go so smoothly to perfectly flat. This is where the entrance sits. On the other side of the pyramid is a similar depression. We might find another entrance there in the future since the flat part marked the entrance. Pictures from: http://www.egyptiandawn.info/chapter3.html
Pyramid of RaDjedef(Djedefre) also has a T shaped shaft underneath.
The layout of Radjedef’s Pyramid at Abu Roash has a T shape underground.
Left from it in above picture seems another structure

Egyptologist, Mark Lehner, studied Radjedef’s pyramid at Abu Roash in his book, ‘The Complete Pyramids’, and concluded that pyramids of the older ‘Djoser’ style (i.e. the Third Dynasty King who built what is now regarded as the prototype to all subsequent Egyptian pyramids; the step pyramid at Sakarra) were orientated north-south, and, from the time of the later Meidum Pyramid onward (which is attributed to Radjedef’s grandfather, Sneferu), were aligned east-west. Lehner and others believe that Radjedef departed from the style of the day and returned to an earlier blueprint when he constructed his pyramid at Abu Roash, for it clearly has a north-south alignment.
