Armenia is a unique country, which has more than 50,000 khachkars (cross stones), made by hand and none of which is not similar to another. Each khachkar has its own pattern and history. For excision of khachkars needed art master, genius talent and a lot of time, because some of them have a height of about two meters and weigh several tons. No nation in the world doesn't use such a powerful and long-lasting way to express their faith in God.

XII - XIII century were the heyday of art carving of khachkars, put them everywhere, and for a variety of occasions, noting events and dates of economic, religious and political life.

The oldest preserved khachkar in Armenia with a known date of creation is a khachkar donated by Queen Katriande, beloved wife of the king Ashot Bagratuni I. It dates from the year 879 and is located in Garni - pagan temple in the 1st century AD

Khachkars are scattered throughout the territory of historical and contemporary country and that is why Armenia often called "Open-air museum".
