The monastery of Saghmosavank is situated atop the very edge of a vertiginous gorge of the Kasakh River. Saghmosavank (literally “a monastery of psalms”) was built in 1215, which is evidenced by an inscription on the wall of Saint Sion Church – the main church of the monastery. There was a scriptorium operating in the monastery in the Middle Ages; the copiers who worked there were famous all over Armenia. The monastery of Sanahin was among their customers.
