Hachkars (or khachkars) are Armenian stone crosses.
‘You encounter these hachkars all over Armenia, for they were the symbols of Armenian existence, or else boundary markers, and also, sometimes, signposts. You can find old hachkars in the most inaccessible places, sometimes high up on the tops of sheer cliffs, and today it is impossible to imagine how their sculptors, most often monks, managed to climb up there.’
