The oldest surviving church of Yerevan. It is a tiny structure constructed in typical Armenian style. Katoghike means "cathedral"; the reason for the incongruity is that the present-day church, dating from XIII century, was incorporated whole into the XVII century basilica - but that one was pulled down in 1936. In 2015, the Catholicos consecrated the large white-and-pink Surp Anna church that is now adjoining Katoghike.
