Tomb S9 is part of a royal necropolis dating back to the late Middle Kingdom – Second Intermediate Period, which is located immediately northeast of the causeway leading to the much bigger funerary complex of Senusret III of the 12th Dynasty,[4] close to the ancient town of Wah-Sut and at the foot of the so-called Mountain of Anubis, a natural hill in the form of a pyramid.

The tomb was covered in sand and proved to have been heavily disturbed, for example, the stone roof of the subterranean chambers had been plundered.

Beyond, lies the burial chamber housing a massive sarcophagus built from three blocks of quartzite sandstone, roughly hewn on the outside, but well polished on the inside.

[4] Small fragments of burned wood were uncovered there during the 1901 excavations suggest that the wooden coffin of the king was destroyed.

Ayrton, Weigall and Petrie believed S9 was a mastaba, because of the enclosing wall which they thought would have held the sand packed on top of the substructures.

[12] At the latter date, during excavations directed by Josef W. Wegner of the University of Pennsylvania, a fragment of a funerary tomb stela bearing a relief naming a king Sobek[hotep] was found inside the enclosure of tomb S10, on the eastern side of the complex, where a funerary temple might once have existed.

[14] Indeed, not only do the fragments of wooden coffin uncovered indicate a late Middle Kingdom date for the construction of S10, but its size means that its owner would have had to reign for long enough to complete it.
