Echmiadzin
The city would nowadays be called Vagarshapat. It is an ancient city. Gurdjieff provides Vagarshapat as alternative name to Echmiadzin.
The city is best known as the location of Etchmiadzin Cathedral and Mother See of Holy Etchmiadzin, the center of the Armenian Apostolic Church. (It is here where the Catholicos of all Armenians resides and carries out his religious duties.) It is thus unofficially known in Western sources as a “holy city” and in Armenia as the country’s “spiritual capital”. It is one of the most common pilgrimage destinations of Armenia.
