At the end of the 11th century there was probably a wooden church in Barva. In the 1100s, the construction of a stone church began. During the 15th century, an armory was built on the south-west side of the longhouse. By the middle of the 17th century, the church was extended to its present length and provided with a new sacristy. At the end of the 18th century it was planned to extend the church further. Instead, from 1796 to 1797, cross-arms were erected to the north and the church thus got its present cross-shape. At the same time, the sacristy was enlarged and the armory from the 15th century was demolished. The flat wooden ceiling of the church room was replaced with thin vaulted wood. The current interior is the result of a thorough restoration in 1942.
