From 1230 forwards the castle was home to knights and caretakers in the Gader Valley, who were appointed by the Bishop of Brixen until 1803. Farmers inhabited it from that point on, until it was converted into the Museum of Ladin History and Culture, and was expanded. The central point of the information is, amongst others, the cave bear, Ursus ladinicus, for which a branch museum in St Kassian was created. A foyer area was added onto the castle with a bar and rooms for temporary exhibitions, area constructed from wood, steel and glass, which with its flat roof goes almost unnoticed next to the superior historical building, and is a good example of a timeless modern construction. Inside, robust wooden flooring and whitewashed walls create a neutral background for various exhibitions and floor-to-ceiling glass-paneled sections of the facade look out onto a gorgeous view.
When a functional change alters the utilization of an historical building, the additional architecture should be up to date, as in this case, yet should also remain peripheral to the historical context.
