Qasr Abu el-Kharaq is a remarkable archaeological site that encapsulates both the ingenuity and strategic importance of ancient desert fortifications. Originally part of the defensive network of the Nabataean Kingdom (150 BC – 105 AD) and later adopted by the Roman army to secure the eastern desert frontier of their Arabia province, this imposing watchtower played a critical role in the Limes Arabicus fortification system.
Location and Landscape
Perched on a hill approximately 3 km northwest of Qasr Bshir, the watchtower offers a panoramic view of a breathtakingly expansive landscape. This region of Jordan, stretching across a staggering 8,000 square kilometres, is defined by gently rolling plains crisscrossed by shallow wadis. These wadis, which channel the scarce desert rainfall westward into the Wadi Mujib, create a unique interplay of rugged natural beauty and barren desert mystery, perfect for exploration and contemplation.
Architectural Features
The structure of Qasr Abu el-Kharaq is both functional and captivating. The rectangular tower spans 22 × 18 metres and is oriented south-southwest to north-northeast. One of its most striking features is the inward-sloping external walls, a clever architectural element that bolsters structural stability. On the northern outer wall, an entryway—still intact to this day—offers a glimpse into the ingenious design. Elevated slightly above ground level, this entrance, as noted by biblical archaeologist Nelson Glueck (1900–1971), suggests the possible existence of steps or a platform originally leading up to it.
At its most well-preserved section, the northern corner, Glueck recorded the tower reaching a height of over eight metres, with 22 layers of stonework still visible. The masonry itself exhibits impressive craftsmanship, comprising hand-cut quarry stones set irregularly yet exhibiting durability. Glueck also discovered remnants of plaster on the south side of the tower, indicating that the walls were originally covered to fill the joints between the stones and protect against weathering.
At the crucial junctions, the corners were reinforced with specially cut stones, a testament to the engineering prowess of the builders.
Mysterious Underground Corridor
The western outer wall of the tower holds a tantalising piece of history. Near its southern end, an opening leads to a subterranean passageway, designed to extend north. This enigmatic feature, blocked further along by debris, invites speculation about its original purpose, whether for storage, escape or as part of a larger network of defensive innovations.
The Enclosure and Older Structures
Surrounding the tower on three sides is the faint outline of what was once a large enclosure, measuring approximately 60 × 60 metres. British archaeologist David Leslie Kennedy later determined that the watchtower was constructed within an existing older structure, its northern wall placed against the enclosure’s boundary. These layers of occupation add depth to the site’s story, blending Nabataean ingenuity with Roman military strategy.
