Gneiss bedrock in Kilonniemi

In Kilonniemi, visitors can see the oldest bedrock area in the EU, gneiss bedrock 2,700 – 2,600 million years old. The remains that can be seen are from the ancient landmass, which over the course of history, several times found itself in the zone where the tectonic plates collided, was folded into a mountain range and was then once more worn down into a smooth rock face. The striped and folded appearance of the gneiss bedrock bears witness to the tumultuous events it has been through. The board next to the rock describes the phases in its history.

Säräisniemi church

Säräisniemi church dates from 1779 – 1781 and is a beautiful wooden church in an idyllic setting. It was built in the parish of Säräisniemi to replace Manamansalo church, which was destroyed in the Russo-Swedish war in the 1590s, as the journey to the next nearest church, in Paltaniemi, was a long one and crossing Oulujärvi Lake was dangerous. Next to the church, under the trees, is a graveyard with old, decorated gravestones. The graveyard also has a memorial to people of the parish who died in the Second World War. The stone footings of Säräisniemi church are in beautifully pleated gneiss, quarried from nearby Pirunkallio. Pirunkallio means “Devil’s Rock” in Finnish. The gneiss is one of the oldest rocks in the European Union. The is an information board of Säräisniemi village by the parking lot of the church.
