Sevanavank is far from being most architecturally interesting monastery. Yet, due to its setting, it is a very appealing place: it stands on top of a hill on a peninsula, giving you great views on stunning lake Sevan. It's true that it receives rather more visitors than the average Armenian monastery, thus some travelers think it misses the atmosphere other places retain. But if you're into images, it is a fantastic place!
An inscription in the oldest of the remaining churches at Sevanavank states that the monastery was founded 874. In the 19th century, it served as a reformatory for monks banished from Ejmiatsin because of their immoral behavior.
