I visited the Great Pyramids of Giza outside of Cairo while on a Mediterranean cruise a few years ago (pre-Arab Spring of 2011). A day around Egypt really is a world history teacher’s dream come true! Admiring the pyramids and Sphinx of the days of the Old Kingdom of Egypt. You can see just how massive the pyramids are by sizing them up next to the tiny tour buses at the base. My students are always shocked by size of these 5000 year old marvels!
