|The unfinished northern pyramid at Mazghuna|
Only parts of the substructure remain from this monument like sliding blocks (green) weighing a good 40 tonnes a piece. The grave chamber (in red) con-tains a huge single block of quartzite (brown) meant to be the sarcophagus.
No traces of its core, casing stones or mortuary- and valley temples are found (and probably none built). Two mud brick walls flank a "causeway" from the east, probably used for transportation of building material. This hardly begun pyramid can be the tomb of Sobeknefru, but no hard evidence like writings have been found to confirm this theory made solely upon the style of the architecture.
