The Haghartsin monastery complex was located in the historic Dzoropor province (18 km north of the city of Dilijan). Haghartsin Educational Center mentioned in bibliography from the XII century in a short period of time it turned into a famous cultural center. The rise of the center is mostly connected with the multifaced acitivity of Khacahatur Taronatsi. According to the legend an eagle was soaring over the dome of the main building at its dedication and thus it became commonly known as the monastery of the playing (or soaring) eagle (“Hagh” means a game while “Artsin” a form of “Artsiv” means eagle in Armenian). There are three churches (the Church of the Holy Mother of God, St. Gregory and St. Stephan’s) built in different historical periods, the two vestibules (one destroyd) and refectory. The oldest of them is St. Gregory Church (around the 10^th century), which is a cross-domed structure. Adjacent to the west is a large vestibule with 4 columns, which dates back to the 12^th century. The last one was built by Ivane Zakaryan. The high sculptures of the angular single-level ceilings of the vestibule are typical of the XIII century. Adjacent to the church is the vaulted chapel from the north, and in the eastern part stands the domed church of St. Stepanos (1244), built of elegant basalt with elegant details. The main church, St. Astvatsatsin, is a domed hall. According to the inscription on the upper part of the southern entrance, it was built in 1281, but the re-arrangment of the lower part of the southern-northern walls, the difference of the model of the church in the high sculpture of the eastern facade from the current structure, suggest that the 1281 structure was restored is: Remains of a ruined structure (probably the vestibule of the previous structure) have been preserved in front of the western façade of the church. In the western part is the refectory, which according to the construction protocol of the south-western entrance was built in 1248. It is one of the two similar structures preserved in Armenia (the other in Haghpat). It is an elongated hall with a composition. The play of interesting arches inside and the restrained sharpness, the soft lighting scattered from the verandas create a majestic complete imagine in its simplicity. The step-plinth that runs along the inner perimeter, which harmonizes with the cornice made above the longitudinal walls, served as a bench. “Minas” is inscribed in the north-eastern corner of the western porch, and the letter “M”, which is often found on the masonry, is probabaly the name of the architect who built it. Haghartsin refectory is one of the best examples of Armenia architecture with its engineering solution. Ruins of other buildings (probably the kitchen, are preserved in the eastern part of the altar. There are several chapels in the territory of the monastery, located on the rocky slopes. The bronze boiler weighing 350 kg found in Haghartsin is one of the masterpieces of metallurgy. The engraving on the crowned edge of the pot indicates the year of manufacture – 1232. Its four chambers are statues of lions, whose legs are also decorated.
