Currently the site is "non-existent" as it is closed due to security problems. From the outside it seems to have largely collapsed and everything is inevitably neglected. I have been told by other visitors I met on the site that this situation has been going on for a long time.
The cave itself can no longer be entered. Above it, however, a platform was built.
