Fusing together Byzantine and Armenian architectural church styles and almost as famous for its location as for the building itself, the date of construction of this particular masterpiece has been lost to history, although surviving documents suggest it’s been standing on the edge of the cliff overlooking the lake since at least 1447. The unusual exterior stone carvings create a good excuse to follow the track around the water to find the place, and the frescos painted on the dome, hidden until 1964, are well worth the pain in the neck you’ll get whilst staring at them in wonder.
