Saqqara is an ancient Egyptian site that was used for burials over thousands of years. Of these, the most famous is the Step Pyramid of Djoser (a king of Egypt’s Third Dynasty) built roughly 4,700 years ago. Visit there today and one of the things you might see, in a building near the Step Pyramid, is a room with glass that protects an inscription. Not any ordinary inscription, this is actually tourist graffiti. Why protect graffiti? As it happens, this example of graffiti was left by a tourist at the site over 3,000 years ago.
