The descending passageway that leads to the Unfinished Chamber is long, narrow,
steep and, without any windows, very dark! When you arrive at the burial chamber, you'll be 20 m (66 ft)
beneath the foundation with over 6 million tons of stone piled above you!
The descending passageway is usually closed to visitors, but you can
take a virtual tour of the passageway and the unfinished chamber.
