The unfinished obelisk is the largest known ancient obelisk and is located in the northern region of the stone quarries of ancient Egypt in Aswan (Assuan), Egypt. It was ordered by Hatshepsut (1508–1458 BC), possibly to complement the Lateran Obelisk (which was originally at Karnak, and was later brought to the Lateran Palace in Rome). It is nearly one third larger than any ancient Egyptian obelisk ever erected. If finished it would have measured around 42 m (approximately 137 feet) and would have weighed nearly 1,090 metric tons (1,200 tons) which is the weight equal to about 200 African elephants.
The obelisk's creators began to carve it directly out of bedrock, but cracks appeared in the granite and the project was abandoned. The bottom side of the obelisk is still attached to the bedrock. The unfinished obelisk offers unusual insights into ancient Egyptian stone-working techniques, with marks from workers' tools still clearly visible as well as ocher-colored lines marking where they were working.
Besides the unfinished obelisk, an unfinished partly worked obelisk base was discovered in 2005 at the quarries of Aswan. Also discovered were some rock carvings and remains that may correspond to the site where most of the famous obelisks were worked. All these quarries in Aswan and the unfinished objects are an open-air museum and are officially protected by the Egyptian government as an archeological site.
