Sannidal Church is a cruciform church built in 1711. The church was located beside the old main road from Oslo to Kristiansand, and the place used to be the centre of the area.

At the graveyard, there are two stone monuments in memory of those that fell during wars. The one at south was for Napoleon's War 1807-1814, when Norway was under Denmark in war against the British ships. The monument outside the entrance of the church is for those who gave their lives in the last World War. Wreaths are laid down at the monuments on 17th of May (Norwegian Constitution Day) and on 8th of May (Liberation Day).

On 1st of September 1772, now existing Sannidal Church opened its door for use. In 1766, Jakob Matsson Lund was chosen to vicar in Kragerø and Sannidal, and we can thank this person for our church today. Sannidal didn't have its own priest at that time because the village was parish of Kragerø between 1732-1868, and it was parish of Bamble until 1732.

Stave Church
There had been church in Sannidal back until the 1200s. A stave church was located at the little hill, south of now existing church. The stave church was dedicated to St. Laurentius, a Roman deacon who led the martyr death at the stake under the persecution of Christians under Emperor Valerian in 258 A.D.

Several objects from the old stave church are found in Sannidal Church today, for example, a lot of the old plank is used in floor and roof. We also find valuable objects at the Norwegian Museum of Cultural History (Norsk Folkemuseum) in Oslo, where also the pulpit and the altarpiece were displayed in the church collections.

Norwegians had also built stave constructions earlier. Stave churches come with Christianity. There are 31 of 750 original stave churches remaining today in Norway. It is natural to guess that in heathen period lay a gudehov (heathen temple) here before the stave church.

Bishop Eystein The Red Book
The first time the church was mentioned in preserved document, was in Bishop Eystein's jordebok (land register), "den røde bok" from 1398. He worked for straightening things out in administration and declining economy of the church. Under his visitation trips, he collected material for a complete list of all that the church owned in Oslo diocese. It was mentioned as "Moo church in Sandhauka valley". Eystein Aslaksson was bishop in Oslo from 1385. This book got a red cover in the 1500s, therefore it's called "den røde bok - The Red Book". The stave church was located at property of the farm Mo. Such farms, with uncomplicated names that describe relationships to the nature, are the oldest in villages.

Weaponhouse
The weaponhouse (church porch) was restored in the anniversary year 1972, after proposal from Directorate for Cultural Heritage. Here we find display of a grave plate moulded at Mørland iron factory in Kjølebrønd, the only visible one left from there. This iron factory was in business from 1641 - 1665. The grave plate is from 1643, and we see "Anna Krefting" written on it. It was probably the wife of Herman Krefting, who ran the iron factory for the last years.

The door of the stave church hangs on the south wall, and the old portals are on the side of the door of the church room. A little sward that was used for protection at the road to the church is also hung up at the south wall, and it reminds us about the proper usage of weaponhouse in the period when people needed to protect themselves at church road. Weapons were prohibited to carry into house of God. It was important to note that sheath knife was not weapon in Sannidal, but a high valued tool. A true Sannidalian carried sheath knife with pride. Many good knife makers are coming from this place.

At the south wall we also find pictures of our recent priests. Torkell A. Tande, the vicar who worked longest here in Sannidal, was also a member of the Norwegian Parliament in several years.

The church room
The pulpit is a gift from Knut Knutsen Dobbe in 1884. It was made first in 1800s in a late Luis 16th style with antique connection. It has rosettes and rows of pearls, and was curved by Peder Olsen, who was "shape-cutter" first at Bolvik factory in Bamble, after that at Froland factory and also at Egelands iron factory.

The baptism bowl, which still is in use, was from the stave church. It has probably come from Gotland in the 1200s. It is made of soapstone.

By the side of the pulpit and the chair of verger, there are two bronze candle stands with two arms from the 1400s. It is made in Gothic style. There are also two smaller bronze candle stands from the early 1600s.

Traffic of sailing ships has been important for Sannidal for a long time, especially when people exported timbers to Holland and England. The ship hang in the church reminds us about it. It is worth to note that it is a battleship with cannons ready to fight for Christ.

Altar
Silverware from the altar of the stave church was locked up today. It is of course very valuable, and some of them have their own histories. A beautiful, oval bread box made of silver was given as a gift to the stave church as appreciation for a miracle rescue of the ship "Patriachen Jacob" of Kragerø outside the Dutch coast in 1703. This history together with the name of the captain, Jakob Jensen, and the ship owner are curved. A silver wine pot was a gift from captain Olle Nielsøn and his sons, Niels and Jon Olesøn, together with 7 other people. It is an elegant Baroque work, with opening and handle made by goldsmith Ole Olsen in Kragerø in the first part of the 1700s.

The paining on the altarpiece came from the old Christi church in Kragerø when it was torn down in 1870. It is from the 1600s and portrays the salvation of the cross.

On the altar table, bible of Fredrik 2nd is lying. It was published in Copenhagen in 1589 with cover of brass mounting. It was at that time given by Niels Jensen Farsjø.
