I stay in Cairo, Egypt. I came to see the three pyramids built 2500 years ago for egypcians, 18 km from here.
I think they are the most impressionants monuments, for many reasons, that turist can visit, that any person can admire. You must to see them very very slowly and with an expert guide.
My love of history makes me complet this trip with a cruise on the Nile river, so important in the ancien life.
