I have often visited the hill with the castle on its top (note it has a sub-gallery of its own), and noticed some years ago that the dilapidated houses that were built on its side were being demolished (in the other gallery I show this on some pictures). Then I read in papers that under these houses an entrance to an underground set of tunnels was found and then, that they must form probably the largest underground city in the region. I kept track of the excavation works, and at one point read that the underground city was open for visits. So in 2019 I tried to get entrance. I was informed that actual visits were one or maybe more years in the future, but when I showed up at the guard’s house I was at least treated to a walk along the outer edge of the underground city, of which I was told that there are 23 layers (ir was it 27?, I forgot) of occupation from top to bottom.

I was not allowed to take pictures, but took some from outside the perimeter, and a very few before I met the guard. I of course intend to return when I can expect to see more of the interior.
