The defense of Tigran Aleksanyan's PhD dissertation titled “The Medieval Fortification of Berd Region” will take place at the IAE.

On February 12 at 14:00, the defense of the PhD dissertation by Tigran Aleksanyan, entitled “The Medieval Fortification of Berd Region,” will take place at a meeting of the Specialized Council 007 “Archaeology and Ethnography,” operating under the Higher Attestation Commission (HAC) at the Institute of Archaeology and Ethnography of the National Academy of Sciences of the Republic of Armenia (IAE NAS RA).

The dissertation is devoted to the study of medieval fortification structures and defensive systems of the Berd region (formerly Shamshadin, later - Tavush, and currently the enlarged community of Berd), located in the northeastern part of the Republic of Armenia.

For the first time, an attempt has been made to conduct a systematic study and comprehensive presentation of the region’s medieval fortification structures, the data related to them, the studies conducted to date, and the views of previous researchers. At the same time, the research sets out to examine the principles of construction of the monuments under consideration, their building phases, chronology, and historical development.
