The center of Armenian Apostolic church – St. Echmiadzin is located 20 km far from Yerevan. The Cathedral of Echmiadzin was founded at the beginning of the fourth century and is one of the oldest churches in the world.

The interior of the church is covered with frescoes, created by Hovnatanyan family. The residence of the Catholicos and the Theological Academy are situated near the Cathedral. Starting from the end of 2018 year till the present day reconstruction works are being carried out, thus the visit of Mother Cathedral currently is foreseen only from outside.

This marvelous temple is a result of skillfulness and brave creativity of Armenian architects of the 7th century. Having been built on several columns, it was able to survive only till the 10th century. When in the beginning of the 20th century this site was being excavated, many specialists could hardly accept its reconstruction model, designed by famous Armenian architect Toros Toramanyan, as it was difficult to believe, that such a huge and complicated construction could have been built those days, and amazingly at that time one of the bas-relieves of St. Chapelle church in Paris came to prove Toramanyan's version; the bas-relief depicts Zvartnots temple with Noah's Ark and it looks like the model, represented by the architect. The site is included in UNESCO Cultural World Heritage List.

Nestled at the foothills of the majestic Mount Ararat, Khor Virap Monastery stands as a timeless testament to Armenia's rich spiritual heritage and historical significance. Its name, translating to "deep pit", alludes to the remarkable tale of Saint Gregory the Illuminator, who was imprisoned in a dark pit here for 13 years before miraculously curing King Tiridates III of a grave illness. Today, visitors are drawn not only to its religious importance but also to the breathtaking beauty of its location. Surrounded by rolling hills and vineyards, with the snow-capped peak of Mount Ararat looming majestically in the distance, Khor Virap offers an unparalleled setting for reflection and contemplation.
