Khachkars are a form of art unique to Armenia. Newcomers may confuse them for gravestones as they tend to be arrayed outside of churches and monasteries but they are actually religious monuments. Khachkars follow a general design pattern depicting the mortal Earth at the bottom, the Church and Christ in the middle, and Heaven at the top. They are symbolic of acceptance of Christ leading man towards Heaven. Echmiadzin hosts a number of intricately carved examples and you'll find many at monasteries around the country such as Novarank and Sevanavank.
