I went there in the late 60’sand got the impression that there was something more important below as the floor appeared hollow, by my sounding it while alone. The owner at the time was not interested in investigating. Maybe modern ground radar would find something nowadays, of great historical importance.
Thanks for your video, I really enjoyed seeing the grotto, we too enjoyed Margate very much recently, it's unique and special. We've just done a gopro walk of the whole town for our youtube page too, hope you enjoy ours in exchange. Thank you we've subscribed.
