 It was not the copy of any street actually in existence in Cairo but an architectural complex made of temporary materials modelled on typical Cairene buildings or parts of them to evoke the atmosphere of the Middle-Eastern metropolis.In order to enhance the authenticity of the Street, a great number of typical inhabitants of Cairo as well as animals (camels, donkeys and snakes) were also brought to Chicago to populate the complex.The idea was not new; it represented a project type which was popular at the time.
