This season, we continued to excavate a previously found pyramid structure.  The monument was built on top of a sandy layer that contains debris from the collapse of the 18th Dynasty pyramid of Siamun. The shaft, located in the chapel, is unique in its stone lining. All of our other pyramid shafts were lined in mudbrick or cut directly into bedrock. As far as we are aware, this is the only structure of this kind in Nubia or Egypt. This building’s construction over earlier debris points to a date at the end of the New Kingdom or the early Third Intermediate/Napatan Period, suggesting both a long continuity and innovation in pyramid building at Tombos.  We plan to continue excavation next season.
