Readers are invited to consult the following book by:
Giovanni Curatola & Gianroberto Scarcia (Translated by M. Shore, 2007). The Art and Architecture of Persia. New York: Abbeville Press. Order from Amazon.
As noted by Professors Curatola and Scarcia a common theory postulates that:
“…domed spaces in Christian buildings in Europe derive from the Armenian model, which, in turn, comes from Sassanian Persia: This can be attributed to geographic proximity and also to the fact that for long periods Armenia was contained within Eranshahr. “ (Curatola & Scarcia, page 92, 2007).
Numerous examples of the earliest church architecture can be seen in Armenia and Iran today:

Iran and Armenia have enjoyed a profound thousands-year long symbiosis at the cultural, linguistic, and artistic-architectural levels – for more see Iran and Caucasia….

Sassanian Iran was to leave a profound legacy on Romano-Byzantine architecture during its tenure in 224-651 AD.

Armenia, Georgia and the Caucasus in general have undergone a profound cultural synthesis which has spanned for thousands for years. As noted by Professor Mark Whittow of Oxford University:
“The oldest outside influence in Trans-Caucasia is that of Persia (p.203)…many of its populations, including Armenians and Georgians, as well as Persians and Kurds, the Transcaucasus had much closer ties with the former Sassanian world to its south and east than with the world to the west (p.204)”. [Whittow, Mark, The Making of Byzantium: 600-1025, Berkley: University of California Press, p. 203-204].

sent to Kavehfarrokh.com by Professor George Nercessian. This was built on the remains of cyclopean walls, where a Zoroastrian fire temple (Armenian Atrushan =Iranian Atar-Roshan) originally stood. There are many similar sites in Armenia where Churches were built on top of Zoroastrian fire temples (Pictures courtesy of Professor George Narcessian). For more on the topic of Armenian-Zoroastrian fire temples consult CAIS: The Armenian Fire Temple of Ani and Payvand News of Iran: The Northernmost Zoroastrian Fire Temple in the World (in the Republic of Georgia).
Goshavank was named after the 12th century philosopher and theologian Mkhitar Gosh who is buried not far from the Church. “Vank” is Armenian for “Cathedral”, therefore Goshvank can be translated as “Cathedral of Gosh”.

The domed architectural style was to attain its own unique style in the Romano-Byzantine Empire, as exemplified by the Holy church of Orthodox Christendom, the Haghia Sophia:
Haghia Sophia (Greek: Sacred Wisdom) Church in modern Istanbul (ancient Constantinople), Turkey.(Source: Turkey Vacation Places)
The site of Haghia Sophia was actually home to three different churches over the centuries. The first was the “Megale Eklesia” (Greek: Great Church) completed by the early 360s but this was completely burnt down and destroyed in the riots of 404. A second church was inaugurated by 415 however this too feel victim to fire in 532 and was destroyed. However, Emperor Justinian I (r. 527-565) ordered a new structure to be built on February 23, 532 – literally just days after the second church had been destroyed. The structure was finally inaugurated in late December 537 with further construction continuing after Justinian’s time.
Note that “Istanbul” is derived from the Greek terms “Es tan Polis” [to the city]. Turkey has done an exemplary job in preserving world heritage Classical sites such as Ephesos, Troy, Cappadocia and Haghia Sophia.
The dome of St Peter’s Basilica in Rome, Italy. This essentially bridged the architectural gap between between the Renaissance and Baroque styles (Source: Rough Guides). The original structure was built in 319-333 and then rebuilt-repaired in the mid-15th century.
