Tanahat, 8th-century monastery in Vernashen, Armenia.

Tanahat is an 8th-century monastery in the Vayots Dzor region, near Vernashen village, made up of two churches dedicated to Saint Stepanos and Saint Nshan. Both buildings are constructed from dark polished basalt stone and follow the Armenian architectural tradition with carved stone details.

The site was originally a shrine built over the grave of Saint Stepanos Syunetsi in the 8th century. Between 1273 and 1279, Prince Prosh funded the construction of the Saint Stepanos church, and the complex later became a center of learning for the surrounding region.

The stone carvings on the church walls show the Prosh family eagle holding a lamb, along with birds of paradise and hunting scenes. These images are visible directly on the walls and tell visitors who funded the building.

The monastery sits in Vernashen village and requires a short walk from the road to reach the complex. A visit in good weather makes the walk easier, as the path crosses open ground between the village and the buildings.

Excavations in 1971 uncovered the foundations of a gavit, a large single-nave church on the south side, and secular buildings; it is presumed that Glazdor University operated in these buildings. The monastery also received many donations of land, orchards and money in the 14th century, and in 1335 Hayrut built a prayer hall here.
