Map of Echmiadzin

Marshrutkas to Echmiadzin (line 203) start from the central (Kilikiya) bus station in Yerevan, at least every 30 mins, more often in busy periods, and take 20-30 mins. It is a fare of 250-300 dram, even if you get off early at the Zvartnots ruins. The end of the line in Echmiadzin is on the corner of Movses Khorenatsi street and Baghramyan street, near the Cathedral complex.

The tourist sights of Echmiadzin are easily accessible by foot. Zvartnots is 5 km east, back towards Yerevan: take a marshrutka (several alternatives to the 203 for this short hop) or taxi.

The following 5 monuments are listed as World Heritage Sights by UNESCO.

• 40.16176944.2911641 Cathedral of Echmiadzin. Founded in 301 by St. Gregory the Illuminator and rebuilt and added to for over 1,700 years, Echmiadzin now is the heart of the Armenian Church, and seat of the Catholicos of all Armenians. The altar is built over an ancient Zoroastrian eternal flame that was uncovered during excavation works in 1950 (now accessible from the museum behind the altar), the inside has interesting frescoes, altar, lamps, and thrones. The intricate bell tower entrance is an addition from the 1800s, and the surrounding grounds have gardens with examples of khachkars from throughout Armenia and further. Near the new entrance gates are a few exquisite khachkar examples from Jugha (in Nakhchivan) - which had by far the largest khachkar collection in the world until they were destroyed during this decade by the Azerbaijani government. The Treasury is well-worth seeing, especially the Roman Geghard or "Spear used at the Cross". Cathedral free, Treasury 1,500 dram. (updated Oct 2018)
• 40.16701944.3096392 St. Hripsime Cathedral. An outstanding example of earlier Christian architecture, this 7th-century cathedral with soaring ceilings and vast interior space was an example for future architects.

• 40.16810444.3048764 Shoghakat Church. At the site of the present day church of Shoghakat, there stood an earlier church of the 6th or 7th century which has not survived. Current building was erected in 1694 by Prince Aghamal Sorotetsi. The name of the church comes from Armenian (Շողակաթ եկեղեցի) meaning "drop of light" because of the ray of light that is said to have come down from Heaven upon Hripsimé's martyrs. (updated Apr 2015)
