Qal’at ‘Unaiza, located in Jordan’s eastern desert, is a small but historically significant Ottoman-era fort built to protect travellers along the Hajj route to Mecca. Constructed in the early 16th century, it served as a military outpost and rest stop for pilgrims making the long and treacherous journey across the desert. The fort was part of a larger system of way stations established by the Ottomans to secure and facilitate the annual Islamic pilgrimage.

Made from local stone, the square-shaped fort features thick defensive walls, corner towers, and a central courtyard with basic living and storage quarters. Though now in ruins, Qal’at ‘Unaiza stands as a symbol of the historic infrastructure that supported Hajj caravans, offering a glimpse into Jordan’s role in Islamic history and the endurance of desert architecture. The site is rarely visited, making it a peaceful destination for those interested in off-the-beaten-path heritage exploration.
