A well protected bedroom
The burial chamber (light blue) was cut down into the bedrock (light brown) and lined with limestone and quartzite (grey).
A saddle vaulted "roof" of two huge limestone blocks (green) weighing a good 50 tons each, was topped by a brick vault within the pyramid's mud brick core (dark brown).
All this was done to protect the pharaoh's mummy in its big quartzite sarcophagus (pink) against the hard pressure of the pyramid's weight and from intrusion from grave robbers.
