The art of khachkar (cross-stone) is the most original manifestation of Armenian medieval culture. Noratus, truly considered to be a forest of khachkars and an open-air museum, displays hundreds of khachkars, the most stunning of which are the so-called "embroidered" ones, typical to the 13th-14th centuries. This is a unique place, where one can reveal the development of khachkarial art in its historical process. Armenian cross-stones art is included in UNESCO Representative List of the Intangible Cultural Heritage of Humanity.

The church of Hayravank is built on a high rock on the shore of Lake Sevan. There is no written testimony concerning the date of its foundation, however, according to the constructional solutions, it has gained its place among the 9th century architectural pillars. This cozy church is built of roughly hewn stone and looks rather modest.

A marvelous scene opens in the north-western part of Lake Sevan, where the peninsula towers over the transparent surface of the lake. Sevanavank monastery was built on the peninsula in 874 by the order of king Ashot Bagratuni's daughter – princess Mariam. The silhouette of the churches against the background of the turquoise lake and blue sky casts unexplainable impression on the visitors.
