 The site, located within the grounds of the great temple of Ptah, was revealed to be a mortuary chamber designed exclusively for the embalming of the sacred bull.A stele found at Saqqara shows that Nectanebo II had ordered the restoration of this building, and elements dated from the 30th dynasty have been unearthed in the northern part of the chamber, confirming the time of reconstruction in this part of the temple.It is likely that the mortuary was part of the larger temple of Apis cited by ancient sources.
