Kerimäki Church sits in a small village 30 km east of Savonlinna and is a remarkable sight: a vast wooden cathedral on a Finnish country roadside, painted yellow with white trim, with seating for 3,400 people in a parish of barely a few thousand. The Neo-Classical design is by the German architect Anders Granstedt; the building was finished in 1847.
The interior is plain and almost overwhelming in scale: long galleries, a tall central nave, a painted altarpiece by the Finnish artist Alexandra Frosterus-Såltin. The church is unheated and is only used in summer (services held in a smaller adjacent church the rest of the year). Open daily June through August; admission is free. A worthwhile half-day excursion from Savonlinna.
