The article organizes and analyzes the historiography of architectural heritage of the medieval city of Ani, the capital of Armenia of the Bagratid period and an important commercial, military-political, and cultural center of Western Asia up to the 14th century. After the flourishing of investigations of the site of Ani during the work of the Russian Ani Archaeological Expedition head by N. Ya. Marr in the early 20th-century, and after the following decades of downtime, the scholar activity began to revive in the second half of the 20th century. From that time, the investigations of Ani have become an attraction for architectural historians from different countries. The geopolitical changes that have taken place since the 1990s have led to a qualitatively new stage in the study of the architecture of Ani, the beginning of work on conservation of the monuments, and the inclusion of Ani in the UNESCO Cultural Heritage List. The study of precisely those decades occurred in the focus of our special attention. As a result, the stages of the last period were identified, as well as the directions of the studies were specified. This work seems important for continuing the investigations and for highlighting the problems of a large-scale monographic study.

The study has been realized by the grant of the Russian Science Foundation, project no. 22-18-00354, in the Moscow State University of Civil Engineering (MGSU), National Research University.
