The burial chamber measures 2.62m × 2.4m with 6.9m total height, corbelled on both sides. A 4.22m deep vertical shaft in the southeastern corner puzzles researchers - Charles Rigano argues it could be an original feature, not treasure hunter excavation. Keith Hamilton notes room for a sarcophagus as large as the Great Pyramid's.
Key facts claimed:
- Chamber entrance is 1.5m high (not 1.6m) and 1.15m wide with enormous stone lintel 1.8m high
- Chamber floor measures 2.62m north-south and 2.4m east-west (5 x 4.5 cubits)
- Total chamber height is 6.9m with 2.7m from floor to first corbel
- Only eastern and western walls are corbelled (8 corbels with combined height of 4.2m)
- Red line runs around walls 52cm above floor - purpose unclear
