“Among Norway’s most striking historical buildings from the Middle Ages are it’s wooden stave churches. Erected at a time when other parts of Europe were raising great cathedrals in stone, they are, in the words of UNESCO, “one of the most elaborate and technologically advanced types of wooden construction that existed in North-Western Europe during the Middle Ages.” The name stave church comes from the fact that they are built with a framework of load-bearing posts (“staver”).
Most stave churches were built between approximately 1130 and 1350. Once there were more than 1,000 stave churches in Norway, but nowadays only 28 remain. They range from small, simple churches to towering structures with multiple naves and elaborate decoration.”- Real Scandinavia.
