Skip the glossy travel brochures; this 800-year-old wooden structure is surprisingly smaller than you expect, but the complex dragon-head carvings on the roofline are wild. Spend an hour walking the perimeter to study the intricate joinery that has survived Norwegian winters since the 1180s. Do not miss the small visitor center nearby for context, or you will stare at the dark timber and miss the point. Go on a cloudy day for the mood.
