The Siwa oasis is a large oasis in the west of Egypt, located about 300km southwest of Marsa Matrouh and 50km east of the Lybian border. It lies 12m below the sea level and measures 9 to 28km in width and 80km in length. Plenty of date palms and olive trees grow in Siwa. Siwa oasis has been settled since the 10th millenium BC and has been part of ancient Egypt since the 26th Dynasty, when a necropolis was established. Alexander the Great visited Siwa during his campaign against Persia to consult the oracle in the temple of Amun. Due to its isolated location Siwa has preserved its unique Berber culture over the centuries. The oasis is idyllic and offers plenty to see, from ruins of ancient temples and sites to desert scenery, the Siwa lake and ancient mud brick architecture.
