Ukko-Koli Hill, Koli National Park

About Ukko-Koli Hill, Koli National Park

The rounded quartzite heights of Koli rise above Lake Pielinen in eastern Finland. Old Karelian tradition held the hills as sacred, and the highest summit bears the name of Ukko, god of the sky and thunder in Finnic belief. Rock formations on the summit were said to be sacrificial stones, and local folklore remembers offerings made here to secure good harvests and weather.

In the 19th century Koli inspired the Karelianist movement, as painters, writers and composers such as Eero Järnefelt and Jean Sibelius sought the soul of Finland in its landscape and its Kalevala mythology. Today it is a national park with forest trails, and the view from Ukko-Koli over the island-studded lake is counted among Finland's national landscapes.
