Who destroyed the facial features on the pyramids of Egypt and why?

Possibly the Christians or Muslims, who would have seen them as idols.


There's also a rumor Napoleon's troops used the sphinx for target practice.Who destroyed the facial features on the pyramids of Egypt and why?
I think you mean the features on the nearby Sphinx, as the pyramids had no facial features. The ones on the Sphinx were destroyed by an iconoclastic Sufi Muslim fanatic in the 1378 as he allegedly saw the local people worshiping the Sphinx. This report was first recorded in the 1400s by the local historian Maqrizi (1364-1442) so his report could be a primary account of something that he witnessed at the age of 14. The Muslim religion prohibits the making of statues of creatures, real or imaginary, and especially prohibits idolatry.





There are extant drawings made in 1737 and published in 1755 that show the the features as already missing, so it is unlikely that Napoleon's troops were the culprits. In fact, Napoleon ordered a major cultural survey of Egypt with illustrations hand drawn in huge books. It seems likely that he would have ordered elite guards to protect the Sphinx.





The damage is so irregular that it is unlikely that it is the result of weathering, especially as some parts of the Sphinx quite near the damaged ones are in relatively good condition.Who destroyed the facial features on the pyramids of Egypt and why?
The idea that the Sphinx was disfigured by religious fanatics or Napoleon's troops using it for target practice is usually seen by historical experts as myths.


The head of the Sphinx has been above the sand for over 4000 years and in that time it has been beaten by the sand and wind which would wear down and weaken the statue. It is likely that some people vandalized the face over the millenia BUT the majority of the damage is time and weather related.
The pyramids never had facial features.





The facial features on the Sphinx simply show the effects of over 3500 years of exposure to sun, rain, wind, and blowing sand.
Many stories about how the Sphinx lost its nose but it was really due to erosion and weather is why.
