The story of Mitford Castle starts with formation of geological layers. In early 11C, Normans built their Motte & Bailey castle, which consisted of massive earthworks and wooden palisade. The castle was then upgraded to a shell keep consisting of chapel, cemetery and five-sided keep before it was burnt down in 14C.

Thinking about it as layers, the museum is just another historical layer. The whole landscape is considered as the museum and consists of hill rings, visitor center, standing stones and forest walk. It is gradually built in defined stages, as first the castle hill has to undergo extensive restorative works.
