To get a glimpse of Christianity in Iran, you may consider visiting St.Stepanos Cathedral near Jolfa city in East Azarbaijan province. The cathedral was built in 9th century and reconstructed during the Safavid era.
The set of Armenian Monastic Ensembles in Iran was registered as a UNESCO World Heritage Site in 2008. Situated in the north west of the country, these consist of three monastic ensembles of the Armenian Christian faith: St. Thaddeus and St. Stepanos and the Chapel of Dzordzor. These edifices – the oldest of which, St Thaddeus dates back to the 7th century-are examples of outstanding universal value of the Armenian architectural and decorative traditions.
They bear testimony to very important interchanges with the other regional cultures, in particular the Byzantine, Orthodox and Persian. Situated on the south –eastern fringe of the main zone of the Armenian cultural space, the monasteries constituted a major centre for the dissemination of that culture in the region.
They are the last regional remains of this culture that are still in a satisfactory state of integrity and authenticity. Furthermore, as places of pilgrimage, the monastic ensembles are living witnesses of Armenian religious traditions through the centuries.
Vank Cathedral of Isfahan, also known as the Church of the Saintly Sisters, is another important religious place for the Armenian community. Construction is believed to have begun in 1606, and completed with major alterations to design between 1655 and 1664. Two major Christian communities in Iran include Armenians and Assyrians. They have a long historical background as Iranian people. They have churches in various parts of Iran and they observe their religious feasts and ceremonies. They have several representatives in Iran’s parliament(or Majlis).
