An-Nekhel Fortress is a 16th-century Mamluk castle located at the center of Egypt's Sinai Peninsula, built by Sultan Al-Ashraf Qansuh Al-Ghuri and subsequently renovated by Ottoman forces in 1705. Strategically positioned as a vital waystation for Muslim pilgrims traveling the Hajj and Umra routes, the fortress served multiple roles including water station, garrison, and regional defense post across several centuries. Excavations at the site reveal evidence of occupation dating to ancient Egypt. The fortress was inscribed on UNESCO's World Heritage Tentative List in 2003, recognizing its historical significance as a medieval pilgrimage landmark and military installation.
