The unfinished obelisk of Aswân lies in a quarry on the south-east side of the mediæval Arab cemetery, being about twenty minutes walk from the Cataract Hotel. It is approached by a small valley leading up south-eastwards from the track of the old Barrage railway. Up to the time of the visit of King Fuad—then Sultan—in the winter of 1920–21, only about 22 metres of the obelisk were exposed to view, the remainder running down into a vast heap of blocks and chips. The curious trench, made round the obelisk for the purpose of detaching it from the rock, has long interested visitors, and His Majesty expressed a desire that the whole obelisk be cleared in order to obtain, if possible, new data as to ancient methods of quarrying, and to expose a unique monument.
