Lastiver is located near Yenoqavan village in Tavush Region. From Pre-Christian times the caves of Lastiver were a sacred place, to which testify the numerous cave pictures. But in the Middle Ages, during the Tartar-Mongolian invasions the caves of Lastiver served as a hiding-place for the village inhabitants. The seal of mankind is put here on the walls of the cave – through dozens of beautiful carvings that depict man and beast side by side as well as images of large and small crosses. It is due to these crosses that some people visit Lastiver today as a place of pilgrimage. At the caves a marvelous view opens: the waterfalls of Lastiver, which are really considered to be wonders of Nature.
