Tatev monastery is situated near the village of the same name in part of Zangezur - ancient Syunik. The monastery was founded in the ninth century in place of a tabernacle well-known in ancient times. The strategically advantageous location on a cape formed by a deep river gorge with precipitous rocky slopes lent itself to the construction of a mighty defense complex here.

The main monument is the Church of Pogos and Petros (Peter and Paul) built in 895-906. It reproduces the type of domed basilicas of the 7th century, but has several new features. Again the location is spectacular, high up in the mountains with great views.
