Unfinished Obelisk in Rose-Pink Granite at 1,170 tons - Aswan, Egypt

In the quarries at Syene (Assuan), whence came the rose-pink granite of the obelisks, still lies one unfinished shaft which, had it been erected, would have been the largest of all. It measures 137 feet and would have weighed 1,170 tons; but there is a flaw in the granite near its centre which explains its abandonment before completion.
