Abu Rawash (also spelledAbu Roach, Abu Roash;Arabic:ابو رواش Egyptian Arabic pronunciation:[ˈæbuɾæˈwæːʃ],Coptic:ⲁⲃⲣⲱⲟⲩϣⲓabrowshi,Coptic pronunciation:[ɑbˈroːwʃi], "flesh of sensual pleasures"[1]), 8 kilometres (5.0 mi) north ofGiza, is the site ofEgypt's most northerlypyramid, also known as the lost pyramid – the mostly ruinedPyramid of Djedefre, the son and successor ofKhufu. Originally, it was thought that this pyramid had never been completed, but the current[when?] archaeological consensus is that not only was it completed, but that it was built about the same size as thePyramid of Menkaure – the third largest of theGiza pyramids. It's believed that the destruction of the pyramid started at the end of theNew Kingdom at the latest, and was particularly intense during the Roman and early Christian eras whena Coptic monastery was built in nearbyWadi Karin. It has been proven, moreover, that at the end of the nineteenth century, stone was still being hauled away at the rate of three hundred camel loads a day.[2]
It is the location of the northernmost pyramid in Egypt (known as Lepsius Number One), the pyramid of Djedefre (also known as Radjedef) and around fiftymastabas (located one and a half kilometres from Djedefre’s pyramid).[3] The excavation report on the pyramid complex was published in 2011.[4]
Its location adjacent to a major crossroads made it an easy source of stone.Quarrying, which began in Roman times, has left little apart from a few courses of stone superimposed upon the natural hillock that formed part of the pyramid's core.
The sedimentary succession in Abu Rawash area ranges in age from Late Cretaceous to Quaternary but is punctuated by several unconformity surfaces.Turonian toConiacian representing the sedimentary succession of Abu Rawashformation that differentiated into six informal units (members) from younger to older as follows:
Sedimentary depositional environment of Abu Rawash Formation are characterized by variable conditions and settings ranging from lower mixed to upperintertidal flat andsubtidal channel for the clastic facies and calm to agitated open marine inner to middle platform for the carbonatefacies.Vertical sequence or facies hierarchy display that the facies sequence of the basal clastic member indicates a progradational peritidal sequence. While those of the rudist-bearing member and limestone member represent a cyclic progradation of high energetic/storm facies above an open marine low energetic fore shoal subtidal facies. The facies sequence of the Acteonella-bearing member reflects two facies associations comprising open marine subtidal assemblage and shoal or bank facies. The latter facies represents the bank that the robust thick shelled Durania arnaudi with the coralline sponge heads accreted local mounds in restricted areasEl-Hassana dome. The vertical facies hierarchy of the flint-bearing chalky limestone member suggests a renewed shoaling of the depositional accommodation, shifting to inner-platform setting and a progradation of mobile bioclasticshoals or banks. The stacking of the sedimentary facies in the Plicatula-bearing member indicates an accumulation in an open shallow sea (inner platform) with intermittent supply of fine terrigenous clastics and clays.

The first burials in the area date to theFirst Dynasty. There is a large Thinite necropolis at the site and a number of objects bearing the names ofHor-Aha andDen were found in the area.[3] A set of radiocarbon data for the reign of Den from the site sets his accession to 3011–2921 BC (1σ).[5]
Unlike the fourth dynasty mastabas of Giza which sit very close to the pyramids and seem to have been built to a plan in advance, the fourth dynasty necropolis at Abu Rawash (cemetery F) lies some distance from Djedefre’s pyramid and the mastabas seem to have been built to order and laid out in a more haphazard manner.[3] There are also a number of burials dating to the fifth and sixth dynasties and a smaller number dating to the Middle Kingdom.[3]
Most of the mastabas are composed of external walls made up of large blocks layered around a bedrock core with the upper sections filled in with loose masonry. On the east side there is a cult niche to the north and a L-shaped chapel to the south. Some of the southern chapels have brick annexes to extend them. Many of the tombs are anonymous but some bear the names of their owners and some artifacts have been recovered also bearing these names; for example an alabaster offering table dedicated to Hornit.[3]
