The Borgund Stave Church is one of the most known and popular stave churches in Norway and it’s a so-called triple nave church. The church was built around 1180, and it’s one of the best preserved of the remaining ones.
On a side note, the Gustav Adolf Stave Church in Hahnenklee, Germany, was built in 1908 with the Borgund Stave Church in mind (means its similar but not a replica). In United States there is a replica in Rapid City, South Dakota, and on Washington Island, Wisconsin.
