Ukonkivi

Ukonkivi, (English: Ukko's rock), is located on the island of Ukonsaari in lake Inari, Finnish Lapland. The Inari Sami name for the island is Äijih. The area of the lake is called Ukonselkä. Ukonkivi was considered by the local Inari Sami to be an extremely important siedi (Inari Sami: siejdi, Finnish: seita) or sacred natural formation and was used as a sacrificial site, perhaps as recently as in the 19th century. The names "Ukko" and "Äijih" refer to sky deities in the Finnish and Sami mythologies, respectively.
