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:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
