Etchmiadzin Cathedral

Etchmiadzin Cathedral – 1st Christian Cathedral in the world

On the twenty-seventh day of the seventh month, Noah's Ark came to rest on Mount Ararat. When Noah emerged from the Ark, he prepared a sacrifice in the Araratian Valley and built an altar for the sacrifice in the place where Holy Etchmiadzin is now located.
The Mother Cathedral was created and built by St. Gregory the Illuminator, the patron Saint of the Armenian Church. In the solitude of the night, given to spiritual thoughts, St. Gregory had a magnificent vision: The Son of God descending from heaven with a golden hammer in his hand strikes the vastness of the ground, and reveals the place where the Holy Cathedral of Etchmiadzin will be erected.
St. Gregory and the family of the St. Trdat the king, led the people to the place of the Descent of the Only Begotten, and built the Mother Cathedral.
Holy Etchmiadzin is also called "illustrated by light", because it was not designed by earthly architects, but rather the Heavenly Architect, who through a luminous illustration, showed how the new church was to appear.
Construction on the Mother Cathedral of Holy Etchmiadzin concluded in August 303.
As a symbol of the Armenian Church and the faith of the Armenians, the cathedral of Etchmiadzin, was proclaimed as such shortly after it was built, and instead of being called by her true name, was often simply referred to as "Vagharshapat’s universal", "Universal church", or merely "First Church".
