Aswan is in the south of Egypt, some 680 km (425 miles) south of Cairo, just below the Aswan Dam and Lake Nasser. Compared to Cairo and Luxor, Aswan is a far more relaxed, if smaller, alternative as a traveller's destination. Aswan is the smallest of the three major tourist cities based on the Nile. Being the furthest south of the three, it has a large population of Nubian people, mostly resettled from their homeland in the area flooded by Lake Nasser. Aswan is the home of many granite quarries from which most of the Obelisks seen in Luxor were sourced. Aswan was the ancient Egyptians' gateway to Africa.
