Sanahin Monastery has part(s) Khachkar
Sanahin Monastery (Armenian: Սանահին վանք, romanized: Sanahin vank') is an Armenian monastery founded in the 10th century in Sanahin in the Lori Province of Armenia.
The name Sanahin literally translates from Armenian as 'this one is older than that one', presumably representing a claim to being an older monastery than the neighbouring Haghpat Monastery, together with which it forms a UNESCO World Heritage Site. The two villages and their monasteries are similar in many ways, and lie in plain view of each other on a dissected plateau formation, separated by a deep crack formed by a small river flowing into the Debed river.
As with Haghpat, Sanahin is frequented by an increasing number of tourists, due to its recent inclusion on the itineraries of a great number of Armenian tour agencies, the beauty of its monastery complex matching that of Haghpat's. The complex belongs to the Armenian Apostolic Church with numerous khachkars (stones with elaborate engravings representing a cross) and bishop gravesites scattered throughout it.History
The first church of the monastery, Surb Astvatsatsin ("Holy Mother of God"), was built in the 30s and 40s of the 10th century under King Abas I Bagratuni. In 966, King Ashot III the Merciful and Queen Khosrovanuysh built the Surb Amenaprkich ("Holy Savior"). Their sons Kiurike (Gurgen) and Smbat, founded a congregation, a high school, invited clergymen, scholars, and writers. The founding abbot was Polycarp, who was succeeded by the scholar Hovhannes.
In 979, by the decree of King Smbat II of Armenia, the monastery complex of Sanahin became the seat of the newly formed bishop of the Kyurikian kingdom (until the middle of the 11th century), Isaiah was ordained diocese of Tashir. Dioscoros Sanahnetsi (1039-1063), proclaimed a "great orator", was one of the patriarchs. During his time, the library and the chapel of St. Gregory were built, the caring school became a large educational center, the library was enriched, many manuscripts were written and flourished. He was studied, taught and created by scholarly monks Anania Sanahnetsi and Hakobos Karapnetsi. In addition to theology, the school taught philosophy, rhetoric, music, medicine, calendars, and other sciences. According to tradition, Grigor Magistros Pahlavuni taught at the school, and the seminary built in the corridor between the churches of Surp Astvatsatsin and Surb Amenaprkich was named after him.
During the Seljuk invasions and their rule, which began in the second half of the 11th century, as well as after the fall of the Kyurik kingdom (1113), the Sanahin monastery experienced a bad period. At the end of the 12th century, becoming a part of the Zakarid (Zakaryan) princes as part of the Tashirk province, the monastery restored its role in the care and scientific and cultural life of the country. Large-scale construction works were carried out in that period. From the 80s of the 12th century to the 30s of the 13th century the vestibules of the Holy Savior and Surb Astvatsatsin churches were built, the bell tower, the bookstore, the guest house (not preserved), the Zakarid family tomb, the high art of Grigor Tuteord and Sargis were erected khachkars, the Church of the Holy Savior was renovated. At the end of the 12th century, the famous Sanahin bridge was built on the Debed river, through which the road leading to the monastery passes, and a spring in the village.
In the 12th–13th centuries, the fathers Grigor Tuteord (which means 'son of Tute'), Hovhannes Khachents (teacher of Zakare and Ivane Zakaryan princes), and Vardan were famous in the Sanahin monastery. The abbot Grigor Rabunapet (Grigor son of Abbas, who was the abbot of Sanahin monastery from 1214) had a great reputation, whose book Because of the broad and delicate writings on the question of the saints also served as a textbook. Rabbi Grigor donated 13 manuscripts to the monastery and wrote other works. The normal activity of the monastery was interrupted again during the Mongol invasions starting from the 1230s and during their rule. At the end of the 14th century the ruling house of the Zakaryans was torn apart, and the village of Sanahin with its surroundings and monastery became the property of the Arghutyan-Yerkaynabazuk (Arghutyan "the Long Arms"; until the beginning of the 20th century).
In the 14th and 15th centuries, the art of writing experienced a new rise in the Sanahin monastery (35 of the manuscripts written there are kept in the Matenadaran). The most memorable is the "Kotuk" of Sanahin (manuscript No. 3032), which contains the chronology of the monastery, valuable information about the history of the congregation.
In the middle of the 17th century, during the leadership of Archbishop Sargis Arghutyan, the main structures of the monastery, which were damaged by earthquakes, were significantly renovated. In 1831, Archbishop Harutyun Ter-Barseghyants, the tribal leader of the monastery, built a single spring near the northern wall (his verse inscription has been preserved on the front), decoded the inscriptions and repaired the structures. At the beginning of the 20th century the activity of the monastery stopped.
During the Soviet rule, Sanahin Monastery, as a historical and cultural monument, was under state protection, and structures were strengthened and restored. In 1998, by the decision of the Government of Armenia, it was handed over to the administration of the Mother See of Holy Etchmiadzin.Khachkars
About 50 khachkars have been preserved in the vicinity of the monastery. The most famous for its historical value and artistic elaboration is the khachkar of Grigor Tuteordi (work of Mkhitar Kazmich), erected in 1184 under the northern wall of St. Harutyun Church, the khachkar erected in 1215 on the tomb of Sargis, one of the victims of the war against the Emirates next to the wall. 
About 190 lithographs from the 10th-19th centuries have been preserved (on structures, khachkars and tombstones). 19 of them are of construction nature (until 1225), the others contain royal, government proclamations, prayers, memoirs, information on donations to the monastery.
