Tomb IGN31, belonging to the type with an undecorated burial chamber, is situated on the western slope of the southern sector of the main massif of the AlBanat necropolis, facing west. The tomb’s vertical development was likely constrained by a natural horizontal plane at a height of about 6 meters. To the right of the opening, there are steps that allowed stonemasons access to the upper parts of the massif. The threshold is raised approximately 1 meter above the current ground level, and the opening is irregularly trapezoidal, with the lower right corner being the only externally worked area, which has been regularized.

The interior structure is square with four pit tombs, of which two are unfinished. The first pit tomb on the left is completely filled with sand, making its dimensions indistinguishable, while the second reaches a depth of about 40 cm despite also being filled with sand. The last two pit tombs have only barely outlined contours and were not excavated. The side walls are roughly sketched, while the back wall is well-finished. The left wall is heavily eroded, making it difficult to determine whether it was never worked or has degraded over time. The right wall is more regular and retains a worked surface, although it is not perfectly planar. A groove, likely created with a pick, is visible at about 1 meter in height along all three walls. The ceiling is significantly degraded, with only a strip about 30-40 cm wide towards the back wall remaining intact.
