Oshakan village has been a holy place since the 5th century, when in 440 due to the duke Vahan Amatuni's efforts the creator of Armenian alphabet Mesrop Mashtots was buried there and a small church was built over his tomb. In the 19th century a bigger church bearing the name of St. Mesrop Mashtots was constructed in the place of the old one. Every year many first class schoolchildren learn the first letter of the alphabet in this church after an oath at the tomb of St. Mashtots.

This exquisite church is considered to be the jewel of Ashtarak. It resembles a monolith pillar due to its small sizes and architectural solutions. It was built in the 7th century and has come to our days almost intact. It has a cross-shaped ground plan from inside and outside.

5 km far from Hovhanavank monastery on the edge of Kasakh river canyon, in the 13th century Vachutian dukes built Saghmosavank monastery. The main church is adjacent to the scriptorium, where many manuscripts have been produced during centuries. Saghmosavank underwent the devastating influence of the earthquake in 1988. The reconstruction comleted in 2000 returned the church its beauty and glory.

Hovhannavank monastery bears the name of John the Baptist. The oldest church here is the one-naved basilica built in the 5th century. In the 13th century under the patronage of Vachutian dukes new buildings were added. The portal of the main church, which is embellished with evangelical motifs, is of great interest.
