Pyramids go out of style
The Giza pyramids were the height of tomb fashion during Egypt’s Old Kingdom. But the nation transitioned into the Middle Kingdom, and pyramids fell out of fashion. Despite its underground chambers, unbelievably complex system of corridors and rooms, they were vulnerable to tomb raiders and thieves. Later, by Ramses and Cleopatra’s time, pyramids were ancient history. Fashionable Pharaohs built mostly hidden, rock-cut tombs. These were less conspicuous and harder (but not impossible) for theives to find. After a while, theives still found many of them. Nevertheless, the age of the Pyramids was over. Therefore, the purpose-built city of Giza Pyramid workers no longer had its purpose. Archaeology on the Pyramid City revels ruins that only stand about ankle to waist deep. The Lehner excavation thinks the city was demolished after the pyramid complex was completed, and the ruins have eroded over time.
