The 2020 war in Nagorny Karabakh brought not merely a shift in the actual borders in the southern Caucasus; it also led to a change in control over several religious buildings or places that had become sacralized as symbols for one or the other side. Using selected examples of sacred places associated with Armenian or Azerbaijani historical memory, this article seeks to cast light on the fate of cultural monuments in war and its aftermath. In connection with the long-lasting conflict, these monuments are forced to undergo a cycle of sacralization, desacralization and reinterpretation of their origins and functions, depending on the approach taken by the winning side. Churches, monasteries and mosques in Nagorny Karabakh thus serve as sad examples of unsuccessful conflict transformation.
