Kihnu Church, built in 1784, is one of the few orthodox churches converted from a Lutheran sacral building. Almost all Kihnu people converted to orthodoxy from 1846 to 1847, the Lutheran church was given to the orthodox congregation by order of Tsar Nicholas I and an onion dome was built on the bell tower. Inside the church, you can admire a simple but beautiful iconostasis that covers almost the entire width of the room.
