Open storage created with the concept of democratization of museums or open museum, are spreading internationally, receiving positive reviews for the participation and accessibility of visitors to the common cultural heritage of mankind. In addition, major national museums in Korea are promoting the establishment of open storage. Open storage, which emerged as a practical way to promote better access to collections by visitors, has now become an important strategy for museums to attract and interest visitors. The spread of open storage is the result of efforts to show the hidden spaces of the museum that the general public has not seen before, such as the storage, laboratory, and conservation science room, which were spaces behind the stage of exhibitions. In a sense, what the museum wants to show through the open storage is not only the collection, but also the open storage itself. The open storage is a great exhibit in itself. The visual experience of being overwhelmed by the scale of the museum's collection is an awe created by humans, that allows us to measure the time and amount of the accumulated collection seen beyond the object, creating a ‘sublime’ experience that arouses fear or admiration. Most of the previous studies related to open storage are limited to a small number of studies related to education or architecture and design, so conceptual and practical research on the function and meaning of open storage is insufficient. Therefore, in terms of the visitors' appreciation of open storages, the purpose of this study is to find out what kind of intentions museums are building and utilizing open storages, and to draw implications by examining the current state of domestic museum exhibitions.
