Ruined citadel, Siwa, Egypt, 1992. An oasis in the Libyan desert, Siwa became famous from the 7th century BC as the site of the oracle temple of Amon. The oracle is said to have confirmed Alexander the Great as both the son of Zeus and the legitimate Pharaoh of Egypt when he visited Siwa before setting off on his campaign to conquer Persia in 331 BC. The ancient citadel is known as the Shali Ghali. Like most of the buildings, it was built from mud brick.
