Sevanavank is a monastic complex located on a peninsula at the northwestern shore of Lake Sevan in the Gegharkunik Province of Armenia, not far from the town of Sevan. Initially the monastery was built at the southern shore of a small island. After the artificial draining of Lake Sevan, which started in the era of Joseph Stalin, the water level fell about 20 metres, and the island transformed into a peninsula. At the southern shore of this newly created peninsula, a guesthouse of the Armenian Writers' Union was built. The eastern shore is occupied by the Armenian president's summer residence, while the monastery's still active seminary moved to newly constructed buildings at the northern shore of the peninsula.

Due to easier accessibility (once it became a peninsula), good highway and railway connections with the Armenian capital Yerevan, a well-developed tourist industry in the nearby town of Sevan, and its picturesque location (although less picturesque than it was before the lake level drop), Sevanavank is one of the most visited tourism sights in Armenia.

According to an inscription in one of the churches, the monastery of Sevanavank was founded in 874 by Princess Mariam, the daughter of Ashot I (who became a king a decade later). At the time, Armenia was still struggling to free itself from Arab rule.

The monastery was strict as it was mainly intended for those monks from Etchmiadzin who had sinned. Jean-Marie Chopin, a French explorer of the Caucasus, visited there in 1830 and wrote of a regimen restraining from meat, wine, youth or women. Another explorer visited the monastery in 1850 and wrote of how manuscripts were still being copied manually.
