This structure has been built over the cave. After you go through this door you have to go down many steep flights of stairs to get to the cave, which has been closed in and has a lock on it. We were in the cave during a service and decided to come back later and try to get some pictures, but of course it wasn't open due to the tourist season not having yet begun. But as we were standing at the door a man carrying a carpet came past and held up two fingers, so we decided to wait two minutes and see. Sure enough, he returned with a key and let us in and nodded that we could take pictures and smiled when we expressed in English our appreciation for his kindess. We didn't stay long, but it was nice to spend a few minutes inside.
