There is a German Lutheran community. There likely are less than 7,000 Protestants. There is also a Georgian Orthodox community and churches.
The Armenian Apostolic Church currently has no community outside the Nagorno-Karabakh Republic. Before the outbreak of the war, Armenians formed the largest Christian population. The Armenian churches in Azerbaijan remain closed, because of the large outmigration of Armenians and fear of Azerbaijani attacks. During the Nagorno-Karabakh War, despite the constitutional guarantees against religious discrimination, numerous acts of vandalism against the Armenian Apostolic Church have been reported throughout Azerbaijan. At the height of atrocities against the Armenian minorities in Baku in 1990, the Armenian Church of St. Gregory Illuminator in Baku was set on fire, but was restored in 2004 and is not used anymore. The Church of St. Gregory Illuminator is the only remaining Armenian church in Baku, all other Armenian churches have been demolished in the 1990s.
