The category of the Stave Church is the only great Norwegian contribution to architecture.
Sigrid Undset attempts to explain why other contributions are scant:
As one of the most extensive and thinly settled countries in Europe, Norway possesses only a few architectural monuments.
There is a good reason for this.
In the Middle Ages Norway belonged to a united, Christian Europe. At that time art flourished here, though the artists themselves are nameless because their work was deeply rooted in the people. Their power of expression streamed from the people through them. This creative power left its imprint on us in the form of buildings and pictures, poems and music.
Then came the spiritual earthquake of the sixteenth century, the Renaissance and the Reformation. Norway was cut off. It became a land apart, and lost touch with the spiritual life of Europe. Much later our increasing world trade again brought us into contact with other countries.
But at least we have the stave churches.
