The Unfinished Obelisk is a huge discarded granite obelisk. Three sides of the shaft, which is nearly 138 feet (42m) long, were completed except for the inscriptions. At 1,168 tonnes, the completed obelisk would have been the single heaviest piece of stone the Egyptians ever fashioned. However, a crack appeared in the rock at a late stage in the process. So it lies where the disappointed stonemasons abandoned it, still partly attached to the parent rock, with no indication of what it was intended for. It does give us an excellent insight into how these massive stone sculptures were made however.
Upon entering the quarry, steps lead down from the surrounding ramp into the pit of the obelisk where there are ancient pictographs of dolphins and ostriches or flamingos, thought to have been painted by workers at the quarry.
