From the Stone Age to the Middle Ages, a dynamic hunting culture was practiced in the River Oulujoki Valley and Lake Oulujärvi areas. A Permanent settlement became more common in the 16th century. Persecutions and wars reduced the settlement, but there are still buildings by the river dating back to the 17th century. Many folk tales from the region have been recorded in the national epoch Kalevala. Lamminaho Farm in Vaala is an exceptionally well-preserved example of the peasant culture. In the farm you can admire buildings and objects from the 18th century. The main livelihoods were agriculture, rapid shooting, fishing and tar production. The farm belonged to the same family for almost 200 years. Today, it serves as a museum farm protected by the National Board of Antiquities. You can explore the peasant culture also in the local museums.
