"Cairo is chaos at its most magnificent, infuriating, and beautiful. From above, the distorted roar of the muezzins' call to prayer echoes out from duelling minarets. Below, car horns bellow tuneless symphonies amid avenues of faded 19th-century grandeur, while donkey carts rattle down dusty lanes lined with colossal Fatimid and Mamluk monuments." – Lonely Planet Guide to Egypt
