The beautiful Siwa Oasis in the far western deserts of Egypt is a remarkable place, for multiple reasons. It’s probably been inhabited, continuously, for 12,000 years. Alexander the Great came here to consult the already renowned Oracle of Amun-Ra in 332BC (some say he is buried here, as he loved Siwa so much). You can swim in Roman cisterns fed by one of the 300 natural springs – which also nourish thousands of date palms and olive groves.
