Think of Egypt and what comes to mind...the Nile and famous ancient structures - the pyramids, the sphinx, the massive Rameses statues, the valley of kings & queens and such like. Less well known is the Bibliotheca Alexandrina (in the Egyptian port city of Alexandria) - one of the most interesting modern structures I have ever come across.
The picture below is one teeny weeny part of the massive structure...scroll down for other views.
In progress.....cleaning of the 160m-diameter glass-panelled roof
The exterior made of Aswan granite
