In Nepal, there is a gorge that is even larger than the Grand Canyon.
There, at a height of 50 meters, there are thousands of holes right in the rock.
No entrances, ladders or climbs. To get there, scientists could only with mountaineering equipment, stumbling upon an ancient city in the rocks.
To answer how a certain people could hollow out a city in the rock a few thousand years ago and how they lived at such a height without any means of ascent, the officials could not say.
