 The first report of the site was given in 1958, upon discovering the so-called "model", a basaltic stone where the city was carved in miniature.The stone is now under roof, under a shelter next to the Museum.It was initially thought that it was a representation of the archaeological site; however, subsequent excavations demonstrated that it is not the case and so far not found a site that matches its design; now it is considered an ideal representation of a city or a sculpted ceremonial center sculpted, taking advantage of the rock morphology.
