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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
