Saint Stepanos Monastery is one of the monuments of Iran which was listed on the UNESCO World Heritage List. The exact date of construction of the fortress and Monastery is unknown, but archaeologists believe that the monastery was approximately built between the 7th and 9th centuries.
From an architectural point of view, there are works of architecture from several historical periods, including Parthian and Roman. The Monastery is located inside a fort that is as strong as the Sasanian period and one of the interesting points is the decorations that exist on its exterior walls. The main materials used in the exterior walls are red and white stone which, apart from the Muqarnas works on the interior walls, gives the church a beautiful reddish appearance.
All Christians in Iran respect Saint Stepanos Monastery, but in fact, it belongs to Gregory Christian Armenians, who gather annually on specific days to perform religious ceremonies at this monastery.
