The Siwa Oasis (Siwi: Isiwan/ⵉⵙⵉⵡⴰⵏ; Wāḥat Sīwah, ) is an oasis in Egypt, between the Qattara Depression and the Egyptian Sand Sea in the Libyan Desert, nearly 50 km (30 mi) east of the Libyan border, and 560 km (348 mi) from Cairo. About 80 km (50 mi) in length and 20 km (12 mi) wide, Siwa Oasis is one of Egypt's most isolated settlements, with 23,000 people, mostly Berbers who developed a unique culture and a distinct language of the Berber family called Siwi.
