Al-Jundī
Jundi is the site of a fortress on an isolated hill in western Sinai, guarding the route across the peninsula toward Aqaba. Known historically as Sadr, the stronghold was built under Saladin. Foundation inscriptions record work on the fortress and its principal buildings between 1183 and 1187. Its hilltop walls overlooked the desert road linking Egypt with the eastern shores of the Red Sea during the wars of the Crusades.
