loser inspection of the wall revealed a narrow indent, which was thought to be some sort of keyhole. Would this allow access to the fabled burial chamber? And how would this secret door open? Research using a x-ray scanner revealed more: The indent and wall were built in front of what appeared to be another solid wall, seemingly as a diversion.
As the scan continued, it was revealed that the true treasure chamber lay right below the archaeologists feet, which could be entered by lifting a mosaic embedded into the floor.
