Attested. Armenia's royal conversion in the early 4th century is attested. The traditional date of 301 comes from later Armenian tradition, and many scholars prefer c. 314. The founding vision is tradition, and the present building is mostly 5th-7th century and later.

Etchmiadzin Cathedral at Vagharshapat, then the Armenian royal city, is the mother church of the Armenian Apostolic Church. Tradition says Gregory the Illuminator founded it after a vision, following King Trdat (Tiridates) III's conversion in the early 4th century. The nearby churches of the virgin martyrs Hripsime and Gayane recall the story of Armenia's conversion.
Source stance: insider. Agathangelos's History of the Armenians (insider, partly legendary), with architecture as a neutral check.
