历史保存中心：轻轻覆盖而非取代的遗迹

Design a historic preservation center inspired by Hedmark Museum. Combine archives, restoration workshops, exhibition spaces, libraries, research facilities, and public walkways into an architectural composition that gently overlays rather than replaces historical fabric. Medieval stone ruins left exactly as excavated, a raw concrete walkway floating above them on slender supports touching nothing, laminated timber roof trusses spanning over the whole site, glass infill between old walls and new roof, cool northern daylight through the gaps, eye-level view along the elevated walkway, 28mm lens, architectural photography, ultra photorealistic, 8K
