Vatnås kirke

Lyngdal Church of 1690 was originally a long church with a rectangular nave and a narrower straight chancel to the east. In the 1730s the church was extended and the chancel and the east wall of the old nave were demolished. The nave was incorporated as the western part of a new cruciform church. A sacristy was built on the north side of the new chancel and a turret was placed over the centre of the cross plan. The interior of the 1730s renovation is well preserved and contains several pieces of 17th-century furniture.

The Holmen church dates from 1853. The basis of the construction is the drawings of the church in Bamble, which were designed by Gustav Adolph Lammers. The church replaced a reconstructed stave church which was about 500 metres east of the presbytery. The stave church was demolished in 1855, but the old cemetery was used until 1890 when a new cemetery was opened. The funeral chapel dates from 1935.

The Bingen Chapel is a long wooden church dating from 1924 and designed by Alfred Christian Dahl. The altarpiece is decorated with the motif "Jesus i Getsemane" and was made by August Klogstad in 1927. The organ is from 1951.
