The cemetery in Humenné was protected by a substantial masonry fence and a locked gate.  We did manage to gain entrance by scaling the fence; however, an intruder would have to be fairly fit and reasonably highly motivated to duplicate our feat.  We were told that the cemetery contained about seven hundred stones, which appeared to correspond with what we saw on the ground.  The stones ran from the top of a significant hill to the bottom.  We saw that most of the stones had been numbered and that some had been braced to prevent them from falling over and sliding down the hill.
