The church is built on clay soil and has a stone foundation. Major portions of the walls are quarried stone filled with lime mortar. The stones of the corners and door are somewhat chiselled.

The church has been through many changes. The southern door, the facade of which is still visible, was walled up already during the Middle Ages. The arch above the chancel - was originally 1.5 meters in breadth, and was widened to 3.8 meters in 1714. The western door had the same breadth as the original arched chancel until the western wall was torn down in 1867. A new church vestibule was erected at the same time, including an enlarged balcony area for the organ. During the same restoration, the windows in both the sanctuary and the chancel were enlarged. The church had a steeple and a vestibule already in 1620. There are references to a vestry already in 1821, but a new one was built in 1867. The vaulted ceilings in both the sanctuary and the chancel, as well as their supports, are dated from the renovations done in 1714. During the last major renovations, 1961-1963, the windows in the northern walls in both the sanctuary and the chancel were walled up. A new floor was laid and vestry built, while the vestibule and gables were newly panelled. Electrical panel ovens replaced the wood stoves at this time.

During the Middle Ages, the church had the main altar within the chancel (most likely dedicated to the Virgin Mary). A side altar, referred to as a cross-altar, was located at approximated the same place where the pulpit stands today. The current interior is influenced by the 17th and 18th centuries. The church had fastened pews already from the 1500s. The altarpiece was a gift from the parish pastor Peder Hansøn Prydz and his wife Karen Olsdatter in 1636. The pulpit is from the same year. The baptismal font, with a vaulted ceiling, is from 1697. In 1791, the church received its first organ. The paintings hung on the northern wall of the sanctuary are from the same period.

The altarpiece from 1636 has painted panels depicting the Lord's Supper and the Resurrection. On the left side of the picture of the crucifixion stands the evangelist Matthew with his symbol of the angel and Luke with the ox. On the right side, stand the evangelist Mark with the lion and John with the eagle. These statues together with Moses and Aaron (to the right and left of the picture of the Lord's supper) are among the finest to be found in Norwegian churches. The altar table is believed to be from 1867 and the framing of the altarpiece is from the 1960's. The original altar railing from 1714 was restored in 1867.

The Pulpit
The pulpit with a vaulted ceiling is hexagonal and is decorated with wooden carvings on the main panels. We find the four evangelists together with biblical texts in Latin. The pulpit rests on a pedestal formed in the shape of a man (Samson) and is believed to be from the 17th century.

The Baptismal Font
The baptismal font from 1697 is beautifully decorated with carved animals` paws. The vaulted ceiling, as the baptismal font, is octagonal shaped and decorated with ornamental acanthus vine on the sides and a figure of Jesus Christ on the top. The baptismal bowl is made of bronze and is believed to have been made in Nürnberg during the 1500's. In the base is a depiction of the Annunciation of the Virgin Mary.

The Organs
The church's first organ, a cabinet organ with 8 registers, was purchased used in 1791 from the Abilsø farm in Oslo. It is believed to have been built in 1786 by the schoolteacher and sexton Niels Samuelsen Dæli in Nes in Hedmark. The organ was situated in the gallery over the altar. This gallery was removed in 1867 and the organ was moved to the gallery in the west. Later, a new organ was left as a gift to the church through the testament of Else Mansdatter Kobbel (1868). This was built by Amund Eriksen of Christiania in 1868 and placed in the western gallery. In 1946 a new Hammond organ replaced both organs. During the restoration of the 1960's, both organs were returned to the church. The organ from 1786 was placed in the chancel and the organ from 1868 in the gallery. The organ in the gallery was restored in 1977 and its range expanded from 4 to 8 octaves.

The Crucifix
On the altar stands a crucifix made by Limoges in France in the middle of the 13th century. It was found during the excavation in 1961 at the approximate location of the present pulpit. The crucifix, which was heavily damaged, has been restored with a new wooden cross. It is made of enamelled brass. On both the arms of the cross and at the bottom of the cross there were originally stones, most likely of coloured glass. These are missing now. From the same period a wooden crucifix was found which is now to be found within the University's Antiquities Collection.

The Paintings
Hangings on the western and northern walls of the sanctuary are paintings from the 1700's. The paintings were originally part of the panelling which faced the congregation. They have the following motifs: The Exclusion/Eviction from Paradise, Jacob's dream, Isaac's Sacrifice, the Four Evangelists/Prophets, the Birth of Jesus, Jesus is Flogged, Jesus with the Crown of Thorns, the Judgement of Pilot, the Crucifixion, the Resurrection and the Ascension.

On the columns beneath the gallery hang two sculptures: St. Peter with the Keys and St. John with the Chalice.

The 24-armed candle chandelier in the sanctuary and the 6-armed one in the choir are gifts from Tora Erlandsen in 1931 and 1934 respectively.

The Psalms board is believed to be from 1780 and is among the oldest in the country. A leather bound chair from the last part of the 1600's was painted again in 1754.

The Church Bells
The Roman bell, cast sometime before 1160, is a treasure in Våler church which few people have the opportunity to see. But we can listen to it, together with the bell from 1799. The latter, cast by Borger Riise of Tønsberg, are 55 cm high, with a diameter of 73 cm. The older bell is 58 cm high and 63 cm in diameter.
