Armenian architecture is characterized by its unique styles and materials, primarily using volcanic tuff stone. This architectural tradition dates back to ancient times, with notable structures like the Temple of Garni and the Cathedral of Etchmiadzin, which reflect a blend of pre-Christian and Christian influences. The design often features intricate carvings, domes, and cross-shaped layouts, emphasizing the importance of Christianity in Armenian culture. Many churches and monasteries, such as the Tatev Monastery, showcase the skillful craftsmanship and artistic expression of Armenian builders throughout history.
