But I was not successful. I was intending to walk there from Mush, along the top of the hillsides that border the sourthern edge of the Mush plain, but heavy rain made me turn back. At the time I assumed that the "Red Church" (or Red Monastery) was Yeghrdut monastery. I do not know the location of the monastery but 38.7761948505, 41.3273423734 might be it (although the orientation is slightly off an east-west direction). 38.7640397182, 41.3046379778 also looks interesting - it appears to be a rectangular enclosure with some structures on the north and south sides, and the shaddow suggests a substantial wall.
