Much of the red granite used for ancient temples and colossi came from quarries in the Aswan area. 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. The site has recently been renovated and equipped with tourist facilities. Nearby is the Fatimid Cemetery, hundreds of mud-brick tombs dating back to the 9th century AD.
