Stave churches are medieval houses of worship, elaborately constructed from timber, which were once the most popular style of church in Northwestern Europe. It is estimated that there were once around 2,000 of these churches dotting the Norwegian landscape, however today there are only 28 surviving. Now, an advancement in the field of dendrochronology has led to a new study that suggests Norway’s historic stave churches are older than previously thought.
David Nikel, from Forbes, reports that the largest discrepancy between the old measurement and the new, known as photodendro, was found in Urnes Stave Church, pictured above, the oldest known stave church and one of Norway’s eight locations protected as UNESCO World Heritage Sites. While originally dated to around 1130, the church is now believed to be as old as 1070.
The team of dendrochronologists studied two other stave churches with photodendro and found similar differences in age. Hopperstad stave church, previously estimated at 1125-1250, was revealed to be much more firmly dated between 1131-1132. Kaupanger stave church was also dated within 2 years, 1137-38, where it was once thought to have been built between 1170-1200.
