The fascination and the "pearl" of mountainous Armenia is Lake Sevan, which is one of the world's greatest high altitude fresh-water lakes. It is about 1900 m above sea level. The lake is of volcanic origin and is surrounded with mountains of 3000 m and higher. The beautiful landscape and the crystal water serve nice preconditions for excellent rest.The lake is also famous for its peninsula and medieval church complex, built in 874.

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.

Goshavank was founded by the famous medieval scientist, fabulist Mkhitar Gosh. The complex consists of several religious and secular buildings. The unrivalled khachkar, put in front of the one-naved basilica, was created by the skillful master Poghos in 1291. Goshavank used to be one of the most famous religious and cultural centers in medieval Armenia.

Haghartsin monastery, situated in the woodlands of Tavush region, represents an indescribable example of blend of nature with architecture. It was founded in the 10-11th centuries, though new buildings were added in the 12-13th centuries. Now it consists of St. Grigor, St. Astvatsatsin (Holy Mother of God), St. Stepanos churches and some other buildings.The refectory, due to its skillful architectural composition, is of great interest. Near Haghartsin there used to grow a huge oak tree, almost at the age of the monastery, completing the whole scene. Unfortunately, only a small part of the hollow has remained till the present day, however, it is still of much interest among the visitors, and preserves the tradition, according to which, when one makes a wish and at the same time manages to pass through the tree (hollow), it is expected to come true in the nearest future.
