This commemorative coin issued by the Central Bank of Armenia is dedicated to the 1700-th anniversary for adopting Christianity in Armenia as a state religion. In medieval Armenia, when the political independence was restored, architecture and sculpture were revived and developed, a new type of monument so called "khachkar" was created in Armenian reality. As a memorial monuments they were placed at the church entrances, halls, road crosses, cemeteries, located on the hills as well as carved or placed on the church walls and mounts. The "khachkars" were regarded as the symbol of soul-saving and Creed.
 

Haghpat Monastery was one of the leading spiritual cultural centers from X to XIII c. Hakhpat Monastery was also a significant monk institution, which contains various ornated khachkars. Haghpat Monastery, also known as Haghpatavank ("Հաղպատավանք" in Armenian), is a medieval Armenian monastery complex in Haghpat, Armenia. Described as a "masterpiece of religious architecture and a major center of learning in the Middle Ages", this venerable institution of the Armenian Apostolic Church was placed on UNESCO's World Heritage List in 1996. The monastery was founded by Saint Nishan (Sourb Nshan) in the 10th century during the reign of King Abas I. The nearby monastery at Sanahin was built around the same time. The monasteries at Haghpat and Sanahin were chosen as UNESCO World Heritage Sites because: The two monastic complexes represent the highest flowering of Armenian religious architecture, whose unique style developed from a blending of elements of Byzantine ecclesiastical architecture and the traditional vernacular architecture of the Caucasian region.
