In the north-western part of Sevan Lake, where the peninsula towers over the transparent surface of the lake, there is a wonderful building. King Ashot Bagratuni’s daughter princess Mariam ordered to build a Sevanavank monastery in 874. The church buildings were constructed from black tuff which probably gave the monastery its name “Sevanavank” – “the Black Monastery”. The silhouette of the churches together with the turquoise lake and blue sky cast an unexplainable impression on the visitors. Today the two black temples of Sevan stand deserted like two guards of this ancient lake.
