In the scope of the Museum, there are three workshops whose task is to protect and restore items belonging to the cultural heritage, as well as to survey climatic conditions in the Museum. The textile workshop has long been the only workshop in Slovenia capable of mending the fragile fabrics. In the 80s of the last century, the workshop started to work on precious tapestries kept in the Museum, boasting the richest collection of tapestries in Slovenia.
Metal workshop takes care of archaeological evidence, artefacts, weapons and armours, while another workshop deals with wooden furniture, artefacts and works of art made of wood.
In general, speaking of professional work, priority is given to the local museum items, although from time to time workshops accept to work as well on items belonging to private or other public institutions collections.
