Tomb IGN18 is located on the western slope of the northern sector of the AlBanat necropolis massif, facing west. It is more set back into the massif compared to tomb IGN17, due to the curved shape of the massif and geological alterations caused by salt efflorescence. The tomb’s facade is recessed by about 3 meters at the lower part and protrudes from the plane created by the clearing trenches by about 50-60 cm. The facade features two half-crowsteps, an Egyptian entablature with a cornice and architrave, and an Ionic entablature with a double-register architrave.

The facade is decorated with two angular pilasters with Nabataean Corinthian capitals, and a cartouche set back 4-5 cm from the surrounding surface. The entrance portal is surmounted by a pediment with a plain tympanum and three acroterion supports. The lower part of the tomb remains unfinished, with incomplete bases and lateral pilasters. A slightly uphill terrace precedes the tomb, featuring 10 pit tombs, 3 of which are incomplete. The internal structure is notable for its unfinished state, revealing various phases of block extraction. The main chamber contains 14 lower blocks and 7 taller ones, creating a regular arrangement within the space.
