In 1250, Bishop Bruno of Brixen founded Bruneck Castle, which served as his summer residence. The town that evolved below the castle walls took on its name. After an eventful history, having been used as a prison and as a school, today the castle houses the fifth Messner Mountain Museum, which focuses on mountain peoples. The historical structure was carefully excavated and restored. The rooms, however, were not sufficient to house the museum and so a section is housed underground, in spaces that were once part of the fortification walls. Modern architectural forms were used for all the additions and new buildings, with concrete, steel, wood and glass having been used as materials. Only the parts that had to be provided as temporary extensions, for example the cashier areas and rooms for temporary exhibitions, were consciously done in wood and may be dismantled at any time.
