The pyramid at Meidum is thought to have been originally built for Huni, the last pharaoh of the Third Dynasty, and was continued by Sneferu. The architect was a successor to the famous Imhotep, the inventor of the stone built pyramid. He modified Imhotep's pyramid design in a way, which is likely to have caused the collapse of the pyramid in conjunction with the decision to extend the construction plan two times in a row, while the pyramid was already under construction. Because of its unusual appearance, the pyramid is called el-haram el-kaddab — (Fake Pyramid) in Egyptian Arabic.
The second extension turned the original step pyramid design into a true pyramid by filling in the steps with limestone encasing. While this approach is consistent with the design of the other true pyramids, a couple of fatal errors were made at Meidum. Firstly, the outer layer was founded on sand and not on rock, like the inner layers. Secondly, the inner step pyramids had been designed as the final stage. Thus the outer surface was polished and the platforms of the steps were not horizontal, but fell off to the outside. This severely compromised the stability and is likely to have caused the collapse of the Meidum Pyramid in a downpour while the building was still under construction.
Some[who?] believe the pyramid to have collapsed not until the New Kingdom, but there are a couple of facts contradicting this theory. The Meidum Pyramid seems never to have been completed. Beginning with Sneferu and to the 12th dynasty all pyramids had a valley temple, which is missing at Meidum. The mortuary temple, which was found under the rubble at the base of the pyramid, apparently never was finished. Walls were only partly polished. Two Steles inside, usually bearing the names of the pharaoh, are missing inscriptions. The burial chamber inside the pyramid itself is uncompleted, with raw walls and wooden supports still in place which are usually removed after construction. Affiliated mastabas were never used or completed and none of the usual burials have been found. Finally, the first examinations of the Meidum Pyramid found everything below the surface of the rubble mound fully intact. Stones from the outer cover were stolen only after they were exposed by the excavations. This makes a catastophic collapse more probable than a gradual one. The collapse of this pyramid during the reign of Sneferu is the likely reason for the change from the usual 52 to 43 degrees of his second pyramid at Dahshur, the Bent Pyramid.
By the time it was investigated by Napoleon's Expedition in 1799 the Meidum Pyramid had its present 3 steps. It is commonly assumed the pyramid still had 5 steps in the fifteenth century and was gradually falling further into ruin, because al-Maqrizi described it as looking like a five-stepped mountain. But Mendelssohn claimed this might be the result of a loose translation and al-Makrizi's words would more accurately translate into "five-storied mountain". A description which could even match the present state of the pyramid with four bands of different masonry at the base and a step on top.
The Meidum Pyramid was excavated by John Shae Perring in 1837, Lepsius in 1843 and then by Flinders Petrie later in the nineteenth century, who located the mortuary temple, facing to the east. In 1920 Ludwig Borchardt studied the area further, followed by Alan Rowe in 1928 and then Ali el-Kholi in the 1970s.
In its ruined state, the structure is 65 m high, and its entrance is aligned north-south, with the entrance in the north, 20 metres above present ground level. The steep descending passage 57 metres long leads to a horizontal passage, just below the original ground level, that then leads to a vertical shaft 10 metres high that leads to the corbelled burial chamber itself. The chamber is unlikely to have been used for any burial.
Flinders Petrie was the first Egyptologist to establish the facts of its original design dimensions and proportions. In its final form it was 1100 Cubits of 0.523 m around by 175 Cubits high, thus showing the same proportions as the Great Pyramid at Giza, and therefore the same circular symbolism. Petrie wrote in the 1892 excavation report  that "We see then that there is an exactly analogous theory for the dimensions of Medum[sic] to that of the Great Pyramid ; in each the approximate ratio of 7 : 44 is adopted, as referred to the radius and circle..". These proportions equated to the four outer faces sloping in by precisely 51.842° or 51° 50' 35", which would have been understood and expressed by the Ancient Egyptians as a seked slope of 5½ palms 
Located nearby is a mastaba of an unknown noble, the burial chamber of which can be entered via a robber's tunnel. This tunnel is steep, extremely narrow and confined. Once traversed however, the chamber and hallway are relatively spacious, and contain the first example of a red granite sarcophagus known in antiquity. Another mastaba is the Mastaba of Nefermaat.
