Al-Meskhouta is the city of Peratum or house of Atum (the sun god) and it was also known as Bitum, and as Tkw beside the Greek name Heroonpolis. It is located in Abu-sweir city about 15 km away from the current city of Ismailia within the range of the valley in which the current Suez Canal was digged, which is known as Wadi Al-Tumailat.       The history of the city goes back to the dynastic era, when peratum was the capital of the eighth district of Lower Egypt in ancient Egypt. Qen-Amun tomb was discovered in 2010 by an Egyptian archaeological mission at Tell Roud Iskandar in Al-Maskhouta. It was found that the limestone gable roof had been broken or removed in the middle, meaning that the tomb had been stormed in the ancient time and its contents had been looted.       This research deals with the manifestations of damage and collapse that tomb of Qen-Amun suffers from, including the burial soil and other phenomena was caused by weathering and various environmental factors after the discovery. But the human factor is the main factor causing the various manifestations of damage and collapse. This research deals also with documentations, analysis and examinations of the current situation of the tomb and the most important conservation and restoration works that took place on the tomb building.
