In the north and south walls of the Queens Chamber there are shafts, which unlike those in the Kings chamber that immediately slope upwards, are horizontal for around 6.6ft before sloping upwards.

The other Relieving chambers were discovered in 1837-1838 by Colonel Howard and J.S. Perring who dug tunnels upwards using blasting power. The floor of the Grand Gallery consists of a shelf or step on either side. In the shelves there are 54 slots, 27 on each side matched by vertical and horizontal slots in the walls of the Gallery.
