Norwegians first began to build stave churches around 1050, as Christianity first began to take hold there during the reign of King Olaf II (995-1030 A.D.). The woodworking craft that flourished in Norway made beautiful, enduring wooden churches that combined Christian symbols and Viking images (such as dragon heads, seen on the eaves above, and the incredible work surrounding the door, below).
The example at Epcot is, of course, a recreation. But while other people throughout Europe built wooden churches, only Norway's are still standing. Twenty-eight of the 1,000 stave churches built there in the Middle Ages are still standing today.
