Collapsed structures against the backdrop of a crane at the Karnak temple in Luxor

When you have an ancient structure such as the Karnak temple in Luxor (built approximately 35 centuries back), there is the chance of tremendous wear and tear, and damage to the structure over the centuries (consider that at another site, the Colossi of Memnon, the entire temple has vanished over the centuries).
In this photo, you see how much of the structure has actually been damaged, with the stone blocks that make the walls of the temple lying around, and broken.
