The Kerimäki Church, built between 1844 and 1847, is the largest wooden church in the world (45 metres (148 ft) long, 42 m (138 ft) wide and 37 m (121 ft) high). There are over 3,000 seats inside the structure, which can hold 5,000 people at a time.
Lake Puruvesi, which lies less than a kilometre away from the church, is one of the clearest lakes in the world. The water is pure enough to be potable.
