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 Church of St Eustace was built between 1532-1632. St Eustace"s is considered a masterpiece of late Gothic architecture. The church’s reputation was strong enough of the time for it to be chosen as the location for a young Louis XIV to receive communion. Mozart also chose the sanctuary as the location for his mother’s funeral. Among those baptised here as children were Richelieu, Jeanne-Antoinette Poisson, future Madame de Pompadour and Molière, who was also married here in the 17th century. The last rites for Anne of Austria, Turenne and Mirabeau were pronounced within its walls. Marie de Gournay is buried there.
The origins of Saint Eustache date back to 13th century. The church became a parish church in 1223, thanks to a man named Jean Alais who achieved this by taxing the baskets of fish sold nearby, as granted by King Philip Augustus. To thank such divine generosity, Alais constructed a chapel dedicated to Sainte-Agnès, a Roman martyr.
