Broken and unfinished obelisk in an ancient quarry at Aswan.
The famous Unfinished Obelisk at Aswan's Northern Quarry - a 41-meter-long and four-meter-wide chunk of stone that was probably abandoned because of a crack in the rock. If completed, the obelisk would have weighed 1,168 tons and would have been the largest ever hewn. You can see many traces of the ancient stonecutters. Blocks would have been detached from the rock by boring holes along a prescribed line, driving wedges into these, and then soaking the wedges with water to detach the block
