Description - One of the most famous stones left behind is the Unfinished Obelisk, more than twice the size of any known obelisk ever raised. Quarrymen apparently abandoned the obelisk when fractures appeared in its sides. However, the stone, still attached to bedrock, gives important clues to how the ancients quarried granite. Much of the red granite used for ancient temples and colossi came from quarries in the Aswan area (500 miles south of Cairo). The Unfinished Obelisk still lies where a crack was discovered as it was being hewn from the rock. Possibly intended as a companion to the Lateran Obelisk, originally at Karnak, now in Rome, it would have measured 120-feet and weighed over 1150 tons when complete.
