Aswan (Assuan) lies 934km south from Giza up the Nile river (about 700 km air-line distance). The granite quarries lie south and southeast of the city of Aswan on the right side of the Nile and cover an area of about 20 km². The granite for the pyramids probably came from the northern part. For the construction of the pyramids the ancient Egyptians only used building stones in perfect condition and that is only a stone which has been split off.
