The Ghar taI-Iburdan complex is located approximately one kilometre to the northwest of Rabat, in the area known as Tal-Lunzjata.

The cave has been excavated into the side of a natural terrace and it has two entrances hidden from view as a result of the natural fall of the land and the heavy vegetation present. The cave complex covers a total area of 1,400 square metres and consists of three main areas connected by a number of corridors.

The plan is of a labyrinthine type, made up of main spaces from which a number of smaller spaces branch out via tortuous corridors. The predominant feature is its curvilinear and irregular layout. The main spaces are furnished with mushroom-type pillars which create large elliptical openings.

A number of small rectangular niches can be noted in the sides of the chambers, intended for holding oil lamps. Quarry marks measuring five to six metres in width can be seen on all exposed surfaces possibly made using a metal hoe. The lower parts of the wall show evidence of a small pickaxe having been used.

The cave was most probably used for habitation during the late Roman period, when international political affairs created the need for more security, which the place afforded in that it was located at a distance from the main urban area and thoroughfares as well as being almost invisible from the exterior.

The troglodytic phenomenon became a main characteristic in the mediaeval period, with a number of other examples recorded, the most famous being Ghar il-Kbir.

Mepa scheduled the Iburdan Cave complex as a Class B national monument as per Government notice 1225 dated December 10, 2010.
