Question

in which ancient structures the 'air shaft' was provided?

Answer 1

The Great Pyramid has air-shafts or just shafts that lead outwards from both the Queen’s and the King’s chamber. The purpose of these shafts is not very well known. Some experts have theorized that these channels served as passages to let the air flow inside the chambers and keep them ventilated while others have suggested that these shafts merely served as passages for the “Ka” (spirit) of the deceased King to travel to the circumpolar stars, which practically never set, hence immortal.
