No. The churches in the picture (from Kizhi island in Karelia) are built in conventional log construction. Stave churches use a post and infill structure. Logs used to be the standard construction method for almost everything in the northern coniferous forest area from Sweden to Siberia.
The Kerimäki Church here in Finland is said to be the largest wooden log church in the world. Built in 1847, it has room for about 5000 people.
