[1][2] As a student, Kalantar in 1907 participated the archaeological excavations of Nicholas Marr in the Armenian medieval capital Ani.

[5] In 1910s Kalantar studied the ancient monuments in the Lori and Surmali regions, the basilica in Zor, headed the excavations in medieval monastery Vanstan (Imirzek) in Armenia and revealed its epigraphic materials.

[2] In 1930s with Alexander Tamanian acted to save the two basilica churches, Katoghike and Poghos-Petros in Yerevan (both were finally destroyed by the ruling regime).

American Journal of Archaeology (AJA 100, 638, 1996) reviewing Kalantar's volume writes: "While Lehmann-Haupt and Marr are often credited with sparking investigations into the history and prehistory of eastern Anatolia and southern Transcaucasia, this compilation* of selected writings and photographs of Ashkharbek Kalantar (1884-1942) makes a persuasive case that it was he who most thoroughly shaped archaeology in the Armenian highlands."

[4] Edik Minasyan, Dean of the Faculty of History at Yerevan State University, said of Kalantar:[4] "Being a brilliant scientist, he was also an outstanding patriot.

He was a soldier of Andranik, and even during the trial when the claim of this fact was already death, he did not change his words, becoming a victim of violence and in 1955 was posthumously acquitted"
