The legend of the founding of Vilnius shows that while hunting the Grand Duke of Lithuania Gediminas stayed overnight in a place where Vilnius now stands. While he was asleep, Gediminas had an unusual dream in which he saw an iron wolf at the top of the mountain . In the morning the Duke consulted the pagan priest Lizdeika about it. He told the Duke that the dream was a direction to found a city among these hills and the howling of the wolf, represented the fame of the future city.
So the Grand Duke of Lithuania, immediately started to build the future capital, and took it the name – Vilnius – from the stream of Vilnia.
