The church of Kerimäki is the world's largest Christian wooden church and has the most spacious interior in Finland. It is 45 meters long, 42 meters wide and 27 meters high. The height of the dome is 37 meters.
Designed by Anders Fredrik Granstedt and built between 1844 and 1847. It had been rumoured that the size of the church was the result of a miscalculation when it was built (supposedly the architect was working in centimetres, which the builder took to be inches), but studies have shown this to be no more than an urban myth. Services are held in a smaller "winter church" (built in 1953) during the winter, as the main building has no heating.
