The largest stone that can be seen in the excavated part of the tunnels (and these are multilevel tunnels, floor by floor, in fact an entire underground city) Man-made and used in the construction of the tunnels is 13 meters long.
The weight of the block is estimated at 570 tons! You can see it in one of the pictures, that’s where the guide is leaning on it with his hand. All this can be called a megalithic construction. The obvious question arises – how, what was all this created with?
Even now modern cranes are not capable of lifting a stone block of that weight, since it was quarried, worked into a block, delivered and placed in its intended location!
