Standing up on the upper part of Dzoragyugh Village and facing the old Yerevan fortress on the left bank of the River Hrazdan, a hermitage-monastery was functioning since the earliest Christian era. This spacious complex, surrounded by a high, fortified wall, was made up of the St. Sarkis, the St. Gevork and the St. Hakob churches, of the buildings of the patriarchal offices and school, of an orchard and of other buildings. 

The St. Sarkis Church was the official seat of the Patriarch, whereas the monastery was the patriarchal inn for the guests.
The St. Sarkis Church, together with the hermitage-monastery, was destroyed by the big earthquake of 1679. It was, however, rebuilt on the same site during the rule of His Holiness Edesatsi Nahabet Catholicos (1691-1705).  The present St. Sarkis Church was rebuilt once again during the period 1835-1842.
With its interior and exterior architectural features this church was the least good-looking among all the churches of the Old City of Yerevan. Its unsightly look did not correspond to its significance as the seat of the Araratian Patriarchal Diocese. During the rule of His Holiness Vazken I Catholicos of Armenians, the church underwent basic renovations and improvements. Based on a plan drawn up by architect Rafayel Israelian in 1972, the reconstruction works of the St. Sarkis Church began and the character of the old building of the church was basically preserved. The fa硤e was covered with Ani orange tufa rocks and engraved with of triangular niches. After R. Israyelian?s death, the construction works were taken over and continued by the co-author, architect Ardzroun Galikian. During the years 1971-1976, the interior look of the church was significantly improved. On the eastern part of the church, a gallery was added for the church choir. As a result of such additions, it was found necessary to remove the old dome and the old drum and to replace them by a much higher dome with polyhedral fan-shaped spire. The construction of the bell tower of the St. Sarkis Vicarial Church was completed in 2000.
The rebuilding of the St. Sarkis Church was made possible by the donation of the benefactors Sarkis Kurkjian and his children, residing in London.

St Gregory the Illuminator church was built by the initiative of the All Armenian Catolicose Vazgen I and was dedicated to the 1700th anniversary of the Christianity adoption in Armenia. The Patriarch personally placed a memorial stone in the place of construction of the church. The blessing ceremony of the church was performed by All Armenian Catolicose Garegin A in 1997 on the day of the Virgin Mary Annunciation feast, on April 7. The church was built by architect Stepan Qyurkchyan's project. It is a church complex comprised of three churches: Mother See, St King Trdat and St Queen Ashkhen chapels. A bell tower with more than 300 columns and a dome were built in front of the church. The remains of St Gregory the Illuminator are kept in the dome. The remains were brought by Garegin the Second in 2000 from St Gregpry the Armenian church in Naples. There are special halls for the receptions and on the ground floor of the church. The draft of the ground has the form of a cross and a facetted dome. It is the largest church among all Armenian churches. The total area of the complex is approximately 3.822 sq m and the highest point is the cross of the church which is 54 m from the ground. The complex is mainly built of monolite iron and concrete and faced with the light orange tufa from the historical capital of Armenia- Ani. With its magnificent look it is seen from many parts of the capital. The church was built by eminent mecenates Alec and Mary Manoukyans, their son Richard and daughter Luiz Simone Manoukyans. The chapels of St Trdat and St Ashkhen were built due to the donations of Nazar and Artemis Nazaryans, Gevorg and Linda Gevorgyans, and the bell tower was built by Eduardo Ernekyan's donation.

The St John the Baptist church was built in 1710 in the place of the medieval church destroyed after a massive earthquake on the high hill of Kond. It was erected with the support of the Yerevanian wealthy man Melik Aghamal. Like other late medieval churches of Paul and Peter (Poghos-Petros), Zoravor and Katoghike this church is a three-nave basilica. The area has a rectangular perimeter and the hall chamber for praying and the eastern altar are located here.
In 1973, architect R.Israelyan presented the draft of the church reconstruction to the All Armenian Catholocis Vazgen I and the project was approved. Unfortunately, in the same year the author died. 10 years later the author’s son, architect A. Israelyan realized his father’s idea. The working project was worked out by eminent architect Baghdasar Arzumanyan and engineer-constructor Avetik Teknejyan. In the 1980s, the engineer-constructor Mikael Hovhannisyan led the reconstruction of the church. The external walls of the dome were faced with tufa stone. Significant work was done inside the church, the main altar was decorated with beautiful sculptures. A platform was constructed for the choir, the ground was covered with marble. In 2000 the educational and cultural centre “Hovhannes Kozern” was founded adjunct to the church.

The Katoghike St. Astvatstsin Church was located in the centre of the Shahar District (presently at the intersection of the Abovyan and Sayat-Nova streets). It was built after the big earthquake, during the years 1693-1695. Built with tufa-stone and cement, it belonged to the three-nave basilica type without a dome. Considering the sizes of its prayer hall (14.0 x 19.3 m), and its outside perimeter (16.4 x 28.4 m), it was perhaps one of the most capacious churches of old Yerevan. The church had entrances on both the southern and western sides.

The walls of the Church lacked the usual means of architectural expression, save the khachkars (cross-stones) that appeared on its walls here and there dating back to the years 1679, 1693, 1694, and 1695.
When the walls were demolished, old khachkars were found in them referring to the years 1472, 1641 and 1642. According to historical studies there had been a church on the same site of the present church traditionally called "St. Astvatsatsin Church".
The hypothesis related to the existence of this old church was completely confirmed during the demolition of the St. Katoghike Church, when the southern and northern walls to which the two vestries were annexed were opened. The oldest inscriptions found on these walls date back to 1264. There are inscriptions engraved on the western façade dating back to the years 1284, 1229 and to the sixteenth century, whereas on the northern walls the inscriptions refer to the year 1609. Consequently, a chapel has probably been built early in the 17th century at the western side of the St. Astvatsatsin Church at whose site the building of the St. Katoghike Church was erected toward the end of the same century. This finding was significant in that it confirms the conclusion that the St. Astvatsatsin Church was the only one of the churches of Yerevan that survived and stood firm after the earthquake.
The St. Astvatsatsin Church, which continues to bear the name of "St. Katoghike", is relatively of small size (5.4 x 7.5 m). Due to the very limited facilities it can offer for the required church rituals, it serves only as a chapel - merely a prayer house.

The Holy Mother of God Zoravor is one of the oldest churches. First it was called Holy Mother of God as there was kept the marvelous “Zoravor” bible. The church was in Shahar quarter of old Yerevan. The chapel and mausoleum of St Anania apostle was in the church and it considered to be a sanctuary. Due to the financial assistance of Yerevanians, patriarch Movses Syunetsi built a church complex consisted of the church, the chapel, cells for monks, the patriarchal residence. It was also surrounded with walls. A theological school was founded here as well. The church was built under Philip Catholicos (1632-1635), however the it didn’t exist for a long time. It was destroyed during the earthquake of 1679. The present-day church was built in the same place, in 1693 due to the donation of the Yerevanian wealthy man Khoja Panos. In the record of 1793 it is mentioned that the St Zoravor church was renovated by the centurion Gabriel under Catholicos Ghukas.

In the Soviet period, after serving different goals, The Holy Mother of God Zoravor church was returned to the worshipers and started working. Confirmed by the Holy Mother See, in 1974-1978 the church was repaired, the ground was tiled with marble, a place was constructed for the choir and a new building was constructed for the clergy. St Anania chapel was renovated as well.

In 1927 refugees from  Melitene (Malatia) of Little Hayq came to Armenia. They established a living quarter at one of the outskirts of Yerevan and named it New Malatia.

In the 1960s a memorial park dedicated to the victims of the Great Genocide of 1915 was laid in Malatia quarter of Yerevan. Later Holy Mother of God Church was built nearby which resembled the main church of historical Melitene (Architect Hrachya Gasparyan). During the construction of the church some soil brought from Malatia state of Little Hayq was mixed with the mixture used in the construction of the walls.

The construction started in 1991 and was dedicated to the heroes fallen in Artsakh battle and to the Armenians of Malatia massacred during the Genocide. The construction was blessed by All Armenian Catholicos Vazgen I. The initiative belonged to the head of Malatia district of that time Vahan Zatikyan. The church has been working since 1998.

The church was founded in 1998, in Nor Nork quarter of the capital. It was built at the initiative of the All Armenian Catholicos His Holiness Garegin II and Sargis Gabrielyan from New York. The priest Garnik Haladjian from New Jersey, USA also contributed to the construction of the church.

The church has a central dome built in traditional Armenian architectural style. The construction involves the architectural elements of Zvartnots, Hripsime and Ani churches. The complex is faced with tufa stone and consists of the main church and the belfry. The church was designed by architect Baghdasar Arzumanyan. It was opened on February 19, 2000. The ceremony of blessing was held on April 30. The painting of Holy Mother hang at the altar is created by the eminent Armenian artist Grigor Khanjyan. The church is three-storeyed. The height of the main dome is 23 m. The prayer hall is multi-cornered and light, with total area of 328 m. Sculptures depicting 12 disciples decorate the hall. There are special niches for lighting candles.

There is also a Sunday school adjunct to Saint Sargis church.

The St. Astvatsatsin Church (it was called ‘"St. Marinos" before) is situated on the height of Nork district. Along with the other monuments of Nork the church was destroyed by the disastrous earthquake of 1679. At the beginning of the XX century the church was restored with the donations of  Ter-Avetikian brothers, the well-known businessmen. In the 1930s, the church became similar to many others, the victim of the religion-persecuting policy.

Though the church was ruined, numerous pilgrims from Nork and form the other localities of Armenia visited it on the holidays dedicated to the Blessed Virgin.

After the proclamation of the new independence in Armenia in 1991, the residents of Nork started the reconstruction of the church with the financial support of the Compatriotic Union of Nork-Marash. In 1995 the St. Astvatsatsin Church opened its doors to the believers.

The St. Gevork Church is one of 10 churches in the ancient Noragavit village, which is preserved nowadays. The church is similar to the St. Zoravor Church by its plan and common volume-space composition. It is a triple-nave, domeless construction with the arched western vestibule and the 12-pillar belfry.

The prayer-hall has entrances from the vestibule and the southern front. Some frescos are preserved on the pillars and walls, which are of interest as late medieval samples of painting. Besides, the stones of the former construction were used during the rebuilding of the church. They can be seen on the walls of the northeastern sacristy and the prayer-hall.

The St. Gevork Church was rebuilt in the XVII century and was fundamentally restored in 1981-1984 under the auspices of the Holy See of St. Etchmiadzin. Mr. Edward Seferian, a benefactor from Argentina, also participated in the restoration of the Church.

The St. Hakob Church was built at the end of the XVII century at the site of the church, which was destroyed by the earthquake of 1679. The St. Hakob Church was reconstructed by the donation of Hakobjan, a wealthy resident of Tiflis. The Diocesan School named after St. Sahak Partev and conducted by Mesrop Archimandrite Smbatyants functioned at the church since 1868.

The St. Hakob Church belongs to the triple-nave basilica type with two couples of pillars, the chief altar in the eastern part and a couple of adjacent sacristies. The church has entrances from southern and western parts. Beautifully sculptured cross-stones (dated of 1504, 1571 and 1621) are fixed on the western front of the church.
In the God-denying years the church was locked and served as a storehouse. Later on, the St. Hakob Church was fundamentally restored by the government and began functioning in 1990.

The Church of Holy Martyrs of Davitashen has been built nearby the bridge of Davitashen. The construction of the church started in 1996-1997, thanks to the sponsorship of Rouben Kevorkian.

The Holy Mother of God church in Avan districts of Yerevan was built in 1996-2000 by the residents of the district: the 1st class counselor of justice Grisha Melik-Sargsyan and the entrepreneur Armen Aghajanyan.

The height of the church is 11 m, total surface is 30 sq m. The church also has a belfry. According to the decision of the Council of Elders of Yerevan, the plot of 600 sq m was allotted for the church construction with the right of unlimited use. The construction started in 1996 and lasted 7 years. Near the church were constructed the house for the spiritual pastor, the residence of the chairman of the parish council and a spiritual centre.
