There are three known rooms, or chambers, inside the Great Pyramid. The lowest chamber is cut into the rock on which the pyramid was built. This chamber was not finished. The other two chambers are higher up inside the pyramid. They are called the Queen's Chamber and the King's Chamber, but these are modern labels as we do not know how the Egyptians were going to use them. The Great Pyramid has two passages, one leading up, and the other down. It is the only Egyptian pyramid to have the two passages.
