When I saw this big tunnel thing the first time, I had no idea what it was – I still don’t but I hiked up it.  It was interesting because there are two churches built into either side (Protestant and something else) – not church buildings but rooms where they held service (?).  And then there was a gigantic cross made of stones once I breached the stairs, and on top of that was a fountain.  It was certainly a hike!  (taken 4.4.2015)
