The
Avarayr Plain is the location of the
Battle of Avarayr in 451, and is described as being along the banks of the
Ṭłmut River (Rūd-e Zangemār,
Iran), apparently the Armeno-Persian frontier at that time. At the time, the Avarayr plain was part of the Armenian region of
Vaspurakan. The plain is located today in northwestern Iran close to the village of
Chors near the border with
Nakhichevan.
