I am asking about the period between the Fall of Western Roman Empire and the Napoleon's invasion of Egypt. My question is: were they treated as tourist attractions and historical monuments, or were they simply ignored?
While you wait for a response that addresses the whole of the period you have specified, this note of mine from an older thread will bring you up to speed with the situation between the construction of the pyramids and the end of the Roman period in Egypt, and this essay, also mine, takes a look at the Giza pyramids in the Arab period, specifically the early ninth century.
