St. Gregory the Illuminator's Church
St. Gregory the Illuminator's Church (Azerbaijani: Bakı Erməni Kilsəsi) is a former Armenian Apostolic church in downtown Baku, Azerbaijan. It was built in 1887 and survived through the radical atheist age of Sovietization, and the conflict between Armenia and Azerbaijan over Nagorno-Karabakh in the late 1980s and early 1990s. Unlike many places of worship that were subject to demolition throughout the Soviet Union in the 1920s and the 1930s, St. Gregory the Illuminator's Church was the only Armenian church that was not demolished. In 1990, during the exodus and deportation of the entire Armenian population from Azerbaijan (as a result of the Nagorno-Karabakh conflict), the church was closed down and damaged, and is no longer open to the public.
From 1990 until 2002, its future status remained undetermined. In 2002, the church building underwent renovation and the building was taken over by the Presidential Administration of Azerbaijan to be used as one of its libraries. The former church was transformed into the archive department of the Department of Administration Affairs of the Presidential Administration of Azerbaijan.
