Kodal Church is a protected long church of stone and timber in the Romanesque style.
After years of decay, in 1691 the church got a new nave in timber as a result of the establishment of the Countship of Jarlsberg. 100 years later, the church inherited the altarpiece from 1634 when Sandar church was demolished, which during modernization in 1854 ended up in the artist's home of the painter Otto Valsta, today the Asker museum.
Today's altarpiece is from 1781.
The church received its first organ in 1893, while new clocks from Nauen Klokkestøperi were installed in 1919.
The church has 225 seats.
