The caves are notable for one reason: Hmmm.......
 * The caves are very large considering their man-made origin: the average floor area of each cave is over a thousand square metres, with heights of up to 30 metres, and the total area covered is in excess of 30,000 square metres.
 * The ceiling, wall and pillar surfaces are all finished in the same manner, as a series of parallel bands or courses about 60 cm wide containing parallel chiselling marks set at an angle of about 60° to the axis of the course.
 * They have maintained their structural integrity and appear not to interconnect with each other.

It could be like a city believed to be mythical, like the Incan city of Vilcabamba was once thought to be.
