The rural church of Kolga-Jaani was evidently built during the last quarter of the 14th century, under the direction of a master craftsman from Tallinn. It was damaged in the Great Northern War and left in ruins for a long period. The 45-meter high steeple was erected in the reconstruction in 1875. The most significant artefact inside the church is a cruficix made probably around the yer 1380.
Between 1890-1917, the man of culture and the great figure of the national awakening period, Villem Reiman (1861-1917), was the pastor of the Kolga-Jaani church and a monument was established in his honour in 1988. On August 16, 1925, a memorial monument was set up to the 17 who had perished during the Liberation War. The statue was destroyed on June 19, 1941 and restored by May 28, 1989.
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
