Koeru Church is one of the oldest medieval churches in Järvamaa with a beautiful Baroque tower. The church was built probably in the mid-13th century and expanded to the three-nave form aroud 1300.
The church was damaged badly in Livonian Wars and again in Great Northern War. It was mainly reconstructed in 1721. The present 43m high tower was built in the end of 18th century. The pulpit, altarpiece and crucifix in the church date from the 17th century.
