Tanum church was probably built between 1100-1130 and enlarged in the early 1700s. The restoration took place in 1900s. In 1674, the Krefting family built a sacristy with burial chambers beneath it on the north side of the chancel. However, this soon became too small, and in 1713 a larger burial chapel was built on the north side of the church, wall to wall with the sacristy. In total, around 40 members of the family were laid to rest in these two tombs. The church was expanded in 1722 and restored in the 1970s.
The richly decorated interior is well-preserved. There are unique 14th century mural paintings. A bell in the tower and two Gothic sculptures are preserved from the Middle Ages. The altarpiece you find in the church today is from 1631, and the font from the beginning of the 1800s.
Tanum church has been a popular subject for many artists. Harriet Backer immortalized the interior of the old Tanum church several times. The most famous painting is 'Baptism in Tanum Church' (Barnedåp i Tanum kirke) from 1892. You can see the painting in The National Gallery (Nasjonalgalleriet) in Oslo.
The church and cemetery have been located to the ancient pagan worship site. There are Iron age burial mounds near the church.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
