Armavir marz is located to the south of the region of Aragatsotn and was named after one of the first capitals of Armenia. Armavir is physically part of the Ararat valley, the largest and the most fertile territory among the forty valleys of the Armenian highland. The climate is sunny, dry and continental. Lake Metsamor is the only natural water reservoir, but in the south east there are swamps and ponds. It has a history of 7000 years.
From twelve capitals, only four have been located here: Armavir, Yervandashat, Bagaran and Vagharshapat. Vagharshapat is located some twenty minutes from Yerevan, the present day capital. After the adoption of Christianity in 301AD, King Trdat III destroyed the pagan temple in Vagharshapat and founded the Cathedral of St. Etchmiadzin in the same place. The name Etchmiadzin comes from legend. According to folklore, St. Gregory the Illuminator saw Christ descending and indicating the location for the cathedral in a dream.. Many other buildings have also been added, including a refectory, the residence of the Armenian Catholic, a lyceum, and a guesthouse. The Churches of Hripsime (618), Gayane (630) and the Zvartnots Cathedral (643-652) were also built in the immediate vicinity. All three churches are impressive masterpieces of Armenian architecture.
